Frontend unit tests cover durations, colours, statistics and health (closes #21)

New table-driven tests in test/unit/main.test.js: humanDuration, the
figure and sparkline colours either side of each latency boundary, a
target's min, max, average and median over an empty history, an
all-unreachable one, a mixed one, one of only answers and one whose
answers have different numbers of digits, and the four health states
either side of their thresholds, with targets found unreachable counted
as timed out. src/main.js exports the four names they need.

package.json gains a test script, which script/frontend-test runs with
the dot reporter and, if a test fails, again with the spec reporter
before failing. NODE_OPTIONS picks the reporter, since yarn appends its
arguments after the test files.

 ## Rationale
 
 When debugging network issues, it's useful to have a persistent at-a-glance view
 of latency and reachability to multiple well-known internet endpoints. NetWatch
-provides this as a single page that does all its measuring in the browser, so it
-can be served from anywhere static files are served. The backend in its Docker
-image only stores the measurements the page reports; without it, the page works
-the same and nothing is stored.

-
-`netwatch-server`, in `backend/`, is a small Go HTTP server that stores the
-reports the page posts. It keeps them in memory and writes them to `DATA_DIR` as
-zstd-compressed files of JSON lines: every minute, whenever 10 MiB are waiting,
-and when it stops. Its routes:
-
-- `POST /api/v1/reports` — takes a report, without credentials; each client
-  address may send a limited number a minute, and the report files are capped in
-  size, the oldest deleted first
-- `GET /.well-known/healthcheck` — answers 200 with `"status":"ok"`, the
-  server's version and its uptime
-- `GET /metrics` — Prometheus metrics behind basic auth, only when
-  `METRICS_USERNAME` and `METRICS_PASSWORD` are set; each client address may
-  make a limited number of requests to it a minute
-
-In the image, the `builder` stage of `Dockerfile` tests it and builds it with
-`backend/script/build`, and `bin/entrypoint.sh` runs it as user `netwatch` on
-`127.0.0.1:8081`, behind nginx. Outside the image, `make run` in `backend/`
-builds it and runs it on port 8080. Its settings, report storage and limits are

-  ([#111](https://git.eeqj.de/sneak/netwatch/issues/111)): each check is a
-  `fetch`, the browser picks IPv4 or IPv6 for each WAN host, and the local
-  targets are IPv4 addresses. The rest of the footer is unchanged
-- 2026-10-04: `README.md`, `TODO.md` and `test/viewport/README.md` say what the
-  tree does (issue #24). The README's Getting Started leads with `make` targets;
-  a new Backend section says what `netwatch-server` stores, its routes and how
-  the image builds and runs it, and points to `backend/README.md` for its
-  settings; the checks are GET requests; the 26 WAN hosts, the four health
-  states, the summary's figures and the features the list lacked are described
-  as the page has them; and its TODO section points here, as does the one in
-  `backend/README.md`, whose open items moved to Future Steps. This file's
-  Workflow branches from `next` and opens the PR against `next`, Status says
-  where the repo stands, and Next Step and Future Steps hold only open work,
-  linked to its issue where one exists. The viewport harness README names Node's
-  test runner, not `vitest`
-- 2026-10-04: in `src/main.js` (issue #102), a target's min, max, median and
-  average latency come from one list of its answers, through the same function
-  the summary's figures use, so the median is written once. The latency color
-  limits are one table in `CONFIG`, read by both the figure's and the
-  sparkline's color. The health thresholds, the debug log's length, the gateway
-  check's timeout, the recovery probe's number of hosts and interval, how often
-  the rows are sorted and the delay before the first sparkline resize are
-  `CONFIG` entries too. A unit test checks the summary's figures. Nothing the
-  page does or shows changed; the footer's color legend still writes the limits
-  out as text
-- 2026-10-04: password guesses at `/metrics` are rate limited (issue #104): each
-  client address, resolved through `TRUSTED_PROXIES` as for reports, may make 60
-  requests to `/metrics` a minute, counted by `go-chi/httprate` apart from its
-  reports; past that it gets 429 and its basic auth credentials are not checked.
-  The limit is a constant in `backend/internal/server/routes.go`. A test uses up
-  one client's allowance on wrong passwords, gets 429 with the right one, and
-  checks that another client behind the same nginx still gets in
-- 2026-10-04: the backend reports errors to Sentry (issue #95). With
-  `SENTRY_DSN` set, it sets up `sentry-go` with the release `netwatch-server-`
-  and its version, reports each panic in a handler through `sentryhttp`, the
-  last of the middleware every request goes through, which panics again so the
-  request still gets the 500 from the panic recovery, and waits up to 2 seconds
-  on shutdown for Sentry to finish sending. A DSN Sentry refuses stops the start
-  with an error naming `SENTRY_DSN`. With it empty, Sentry is not set up and
-  nothing is sent to it
-- 2026-10-04: a target's name and URL and a debug log message show as the
-  characters they are and are never read as HTML (issue #29): a host row escapes
-  the name and URL it writes into its markup, and the debug log sets each line
-  as text. A unit test checks a target whose name and URL hold `<`, `>`, `"`,
-  `&` and `'`. `README.md` no longer calls `CONFIG` frozen: the interval menu
-  sets its `updateInterval`, and the values computed from it follow. `AppState`
-  declares the recovery probe's two properties, the sparkline axis functions
-  lose the parameters they did not use, and the comment on a target's history
-  names both kinds of entry it holds. Nothing the page does changed
-- 2026-10-04: a dependency can be added without running yarn or go by hand
-  (issue #45): `make add-dependency PACKAGE=<name>@<version>` shims to the new
-  `script/add-dependency`, which runs `yarn add --dev`, so `package.json` and
-  `yarn.lock` change together, then `yarn install --frozen-lockfile`; the same
-  command moves a package to another version. `make tidy` shims to the new
-  `script/tidy`, which runs `go mod tidy` in `backend/`: a Go module is added by
-  importing it, or moved by editing its `require` line, then `make tidy`.
-  `script/bootstrap` still installs with `--frozen-lockfile`
-- 2026-10-04: the backend serves Prometheus metrics (issue #94). With
-  `METRICS_USERNAME` and `METRICS_PASSWORD` both set, it records request
-  duration and response size through `go-http-metrics` and serves them, with
-  Go's runtime and process metrics, at `GET /metrics` behind basic auth with
-  those credentials; nginx passes `/metrics` to it as it does `/api/`. With
-  neither set there are no metrics and `/metrics` is 404; one without the other
-  stops the start with an error naming both, and so does a `METRICS_USERNAME`
-  containing `:`, with an error naming it. Only requests that reach the health
-  check or `POST /api/v1/reports` are recorded, not `/metrics` itself and not
-  every request as `GO_HTTP_SERVER_CONVENTIONS.md` shows, because the labels are
-  the request's path and method, which clients can make up without end. For
-  that, `POST /api/v1/reports` is now registered by its full path instead of
-  inside a `/api/v1` route group; it answers as before
-- 2026-10-04: `script/` and `Makefile` follow the org models (issue #28):
-  `make dev` shims to the new `script/dev`, the Vite dev server, and the new
-  `make build` to `script/build`, the frontend production build.
-  `.prettierignore` no longer leaves out `backend/`, so `make fmt` and

-### Metrics
-
-With both `METRICS_USERNAME` and `METRICS_PASSWORD` set, the server serves
-Prometheus metrics at `GET /metrics` to requests with those as their basic auth
-credentials, and answers any other with 401. For each request that reaches the
-health check or `POST /api/v1/reports`, those the rate limit refuses included,
-the metrics record its duration and response size, labelled with its path,
-method and status; they also count those requests in progress, and include Go's
-runtime and process metrics. No other request is recorded: not those to
-`/metrics` itself, and not those answered before they reach either route, such
-as a CORS preflight, or a request refused with 404 for a path no route has, 405
-for a method its route does not take, or 413 for declaring a body length over
-the 1 MiB limit. A report whose body goes over the limit without declaring its
-length reaches the route, is answered 413 there, and is recorded with that
-status. Clients can make up any number of paths and methods, and each would add
-labels to the metrics for as long as the server runs. With neither set, nothing
-is recorded and `/metrics` answers 404. One without the other stops the server
-from starting, with an error naming both; so does a `METRICS_USERNAME`
-containing `:`, which basic auth cannot carry, with an error naming it.
-
-`/metrics` is rate limited, so that its password cannot be guessed quickly: each
-client address, resolved through `TRUSTED_PROXIES`, may make 60 requests to it a
-minute, whatever their credentials. Past that it gets 429 with
-`Retry-After: 60`, and its credentials are not checked. The minute slides as it
-does for reports (see [Report limits](#report-limits)), so a scraper polling
-every 2 seconds or less often is never refused. This allowance is apart from the
-one for reports.
-
-### Sentry
-
-With `SENTRY_DSN` set, the server sends its errors to that Sentry project: each
-panic in a handler is reported there, under the release `netwatch-server-`
-followed by the server's version, and the request still gets 500 from the
-server's panic recovery. On shutdown the server waits up to 2 seconds for Sentry
-to finish sending. A DSN Sentry refuses stops the server from starting, with an
-error naming `SENTRY_DSN`. With it empty, Sentry is not set up, and nothing is
-sent to it.

 ## TODO
 
-The to-do list, this backend's open work included, is [TODO.md](../TODO.md) at
-the repo root.
+- Add integration test that POSTs a report and verifies the compressed output
+- Add report decompression/query endpoint
+- Add metrics (Prometheus) for buffer size, flush count, report count
