sneak ddbe8cd8df Drive the archive reopen debounce test from a clock (closes #190)
check / check (push) Waiting to run
Details 
The archive writer now reads the time its reopen debounce is
measured on from a clock field, time.Now outside tests. The
debounce test moves that clock instead of sleeping past a real
2 second window, so a slow host between the two quick writes can
no longer turn a correct result red.

## Third-party browser assets
The web UI serves one third-party script, Alpine.js, in its CSP build: the npm
package `@alpinejs/csp`. The pages' Content-Security-Policy forbids eval, which
the standard `alpinejs` build needs to run the expressions written in the
markup. The CSP build runs no expressions, so every Alpine directive in
`templates/` only names a property or method of a component registered in
`static/js/app.js`: `x-data="collapsible"` and `@click="toggle"`, never
`x-data="{ open: false }"` or `@click="open = !open"`.
A browser test in `internal/server` loads the webhook page and the event log
under the real policy and checks that: both add forms stay hidden until Add is
clicked; choosing Slack in the add target form leaves the HTTP fields out of
what it submits, also after leaving the page and going back to it, when the
browser restores the choice; the Copy button beside an entrypoint URL reads
"Copied" once clicked; an event expands and collapses, and so do a delivery's
attempts inside it; and at phone width the menu button opens and closes the
mobile menu. It also fails if the browser reports a console warning or error,
an uncaught exception, or anything the policy refused. `make check` and the
image build lint it but do not run it, and `make test` leaves it out (its file
is built only with the `browser` build tag). Run it with `make test-browser`
after changing `templates/` or `static/js/`: that builds `Dockerfile.browser`,
which runs the test in a digest-pinned headless browser image, so the host
needs no browser.

## Rationale
@@ -2033,29 +1992,6 @@ Because each `database` target has its own archive file, a target's
webhook with different expiries keep two archives, each pruned on its
own schedule.
Each `database` target on the webhook page has a **Download** button,
which returns its archive as one gzipped JSON file,
`archive-{webhook_name}-{target_name}-{YYYYMMDDTHHMMSSZ}.json.gz`, the
names made safe as above and the time in UTC. The file holds one
object: `webhook` and `target`, each an `id` and a `name`;
`exported_at`; and `archived_events`, one object per archived row with
every column, keyed by column name. A body that is not valid UTF-8 is
written in base64, with `"body_encoding": "base64"` beside it. An
archive that does not exist yet, or was moved away, downloads with an
empty `archived_events`; the download never creates the file.
The download streams: each row is read and written out compressed
before the next is read, so neither the archive nor the JSON is held in
memory. It reads on a connection of its own, inside one read-only
transaction, so the file holds the archive as it stood when the
download started, and archive writes go on meanwhile, since under WAL a
reader never blocks a writer. While it runs, the `-wal` cannot be
checkpointed past what it reads, so a long download lets the `-wal`
grow. It finds the file by the stored names under the lock that webhook
edits, target edits and target creation hold, and lets go once the file
is open: a rename during the download moves the file without affecting
it.
Deleting a webhook releases its archives: the delivery engine's cached
archive writers are dropped and their file handles closed, so nothing
lingers after the webhook is gone. The archive **files themselves are

microseconds it needs.
That reserve belongs to the tail hooks, not to the server hook, and
the server hook could take it in two ways. The hooks before it may
already have spent part of the budget, so a full 3-second drain
would come out of the reserve; the drain is therefore also bounded
by whatever is left on the stop context minus the reserve. And the
Sentry flush runs after the drain **inside the same hook**, and
`sentry.Flush` takes a bare duration and honours no context, so an
unreachable Sentry endpoint would add its own timeout on top of a
full-length drain and consume the whole sequence budget by itself.
It is clamped the same way, and skipped when that leaves too little
to be worth attempting — so a full-length drain means Sentry events
are dropped rather than the database close being skipped.

This does not make the database close unconditional. A slow
`ArchiveSweeper` or `RetentionReaper` is enough to cut the shutdown
short, not only one that consumes the whole budget: what they spend
comes out of the drain first, so after 2 seconds of theirs a request
still in flight gets 1 second to finish, and after 3 it gets none.
Past 3 seconds they spend the reserve itself, and one that takes the
whole budget skips every hook after it, the database close included.
This does not make the database close unconditional: a wedged
`ArchiveSweeper` or `RetentionReaper` still runs first and can
consume the whole budget on its own.
