Marc-André Bombeck 4ff3f3eb5d test: property tests for zones, statistics, cadence, crypto and backups ...

fast-check properties with one shared configuration (tests/property/): a
fixed seed on every pull request, a fresh one and more cases at night through
FC_SEED and FC_NUM_RUNS, and a printed seed with the shrunk counterexample on
failure.

- Time zones: wall clocks agree with Intl in twenty awkward zones, a wall
  clock maps back to an instant showing it, a skipped hour resolves forward
  on the same day, every instant lies inside the window of the day it is
  filed under, and day keys shift and count as inverses.
- Statistics: every median in the tree says the same number, medians and
  spreads obey order, shift and scale, a least-squares fit recovers an exact
  line and composes from stored sums exactly, and the segmented regression
  recovers a noiseless interrupted line.
- Cadence and compliance: weekly and daily schedules expect exactly what a
  day-by-day oracle expects, in any zone and on transition days, and the
  rate stays within bounds and never falls when a missed dose is taken.
- Encryption: every codec opens what it sealed under the key it names,
  rotation moves the key id and nothing else, and a tampered value never
  opens to anything but the sealed bytes.
- Backups: randomly generated accounts come back from a disaster-recovery
  restore with an identical canonical dump of every generated table.
