Real one-line docstrings stating what each test pins down. Files that
would pass 250 lines moved whole classes into _part2 siblings
(sick_panel, earned, poke_server, shutdown_reading,
manual_workout_dialog).

- addopts: -n 4 --dist worksteal (fixed, not auto: 24 workers would break
capped.sh's 4 GiB). CI's own -n auto still wins.
- coverage core = sysmon (PEP 669): ~40% less tracing overhead, same data.
- shutdown ceiling invariant: one plain-function patch of earned_units per
day instead of a MagicMock per unit (~5000 per case); every day and every
case still checked.
- poke/web server tests: serve_forever(poll_interval=0.01), so shutdown()
no longer waits 0.5 s per test.
- autouse _no_real_ntp: check_clock_skew sent real UDP to pool.ntp.org from
every verification test, and a lost reply cost a random test 5 s.
- temperature hard-timeout test: pins the default to 5 s and times the
mechanism at 0.1 s instead of waiting 5 real seconds.
- _xvfb_reexec: Xvfb -displayfd instead of xvfb-run's fixed 3 s sleep.
