fix(dates): show the year whenever a date is not the current one

Sweeps every surface that renders a date from before this year without
a year suffix — illness episodes/flares/day-logs, lab and custom-metric
charts, the mood chart family, medication titration/side-effects/dose-
history/next-dose captions (incl. the Dec→Jan rollover), cycle
predictions and history, the BBT chart, the intraday-pulse day-nav, the
date-range filter chip, and the nutrient/compliance charts. Each now
routes through dateShortSmart / dateWithWeekdaySmart (format-locale.ts)
or the matching date-format.ts helper, which add the year only when it
differs from the current one — mirroring the workout list's existing
model instead of a bare "19.02." that reads as this year's.

Also fixes two sites that bypassed the app's locale entirely: the
trusted-devices expiry (bare toLocaleDateString, host locale) and the
admin token-name timestamp (hard-coded de-DE + Europe/Berlin) now both
render through the user's own locale, hour-cycle, and timezone
preference.
