sneak b80c8fd214 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 empty, all-unreachable and
mixed histories, and the four health states either side of their
thresholds. 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.

Model: opus-5-5
