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 and one of only answers, 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.

tick drew no row until the round's slowest check ended, up to 24
seconds at a 30-second interval since checks time out at 80% of it.
Each check now pushes its sample and redraws its row as it ends. When
the last check ends, every row is redrawn, so none still reads "paused"
after a pause and resume, and sorting, the summary, the health box and
offline detection run once. A check that ends while paused or after its
round is given up draws nothing, and the first round is still discarded
as a whole. The row is looked up when the check ends, as a pin click can
re-sort the rows mid-round.
Unit tests run tick on the mocked clock against a stand-in page.

Each target check now times out after 80% of the refresh interval, 24
seconds at 30 seconds, where it was capped at 3 seconds, so slow, far
targets are recorded with their real time. Rounds never overlap: a
round gives up the last round's checks if they are still waiting, which
happens only when a round starts early, after an interval change or
when the recovery probe finds a target answering. The probe still
checks every half second, giving up its previous checks, so they do not
pile up.
The frontend has its first unit tests, run by script/frontend-test with
Node's built-in test runner on a mocked clock. index.html now links
src/styles.css, which src/main.js imported, since Node cannot import
CSS.
