* feat(settings): per-user date and time display format settings
Add ui.date_format (auto, DD/MM/YYYY, MM/DD/YYYY, YYYY-MM-DD) and
ui.time_format (auto, 12h, 24h) as validated user-scoped settings, a
shared preference-aware formatter module (web/src/lib/datetime.ts)
synced via DateTimeFormatProvider, a Date & time section in Appearance
settings, and convert all absolute date/time display call sites to the
shared formatters.
Closes#303

* fix(settings): make loaded API settings authoritative for date/time formats
Address adversarial review: once the authenticated settings request
resolves, a missing ui.date_format/ui.time_format key means "auto"
instead of falling back to device-wide localStorage (which could carry
another user's preference), and failed saves roll back through the
query cache. Layout and AdminLayout subscribe to the format store so
all routed pages re-render live when the preference changes.

* fix(settings): reliable re-render and rollback for date/time format changes
ReactiveAppRoutes re-renders the routed page tree when the format
preference changes (a Layout-level subscription cannot re-render stable
children elements); memoized AdminLogs rows and the out-of-route
PlayingNextScreen subscribe directly. useSetSetting now rolls back only
the mutated key on error and invalidates the settings list on settle so
overlapping saves cannot resurrect stale values.

* fix(settings): guard same-key rollback against newer optimistic saves
Roll back a failed setting save only while its optimistic value is
still current in the cache, invalidate the detail query on settle, and
add a regression test for overlapping same-key mutations.

* fix(settings): owner-bind the datetime format warm start, pad 24h hours
Address PR review: the localStorage warm start is now tagged with the
user id that mirrored it and is ignored for a different authenticated
user, so a failed settings request can no longer leak another account's
format on a shared browser. The 24h branch of formatTime defaults to
2-digit hours ("09:04") since h23 alone does not guarantee padding in
every locale.
