Add a TimeFormatPref (Auto/12h/24h) preference. Auto follows the device's
24-hour system setting; the others force a clock app-wide. The resolved
convention is provided once at the app root via LocalUse24HourFormat, so
every in-app time label reads it without per-screen plumbing.

A shared, pure TimeFormat helper (formatTimeOfDay / formatMinuteOfDay /
formatHourLabel / timeOfDayFormatter) is now the single source for all
time-of-day rendering. Routing every site through it also fixes a
pre-existing inconsistency: the week/day timeline gutters and the agenda
screen + widget hard-coded 24h, while event detail/edit/search/reminders
followed the locale — so a 12h-locale user previously saw mixed formats.

Covered: week & day timelines (gutter + event blocks), agenda screen and
widget, event detail/edit, search, and reminder notifications.

Closes #6 (Codeberg)
