The event-form (and Settings) time picker seeded is24Hour from the
system TIME_12_24 override / device locale, ignoring the app's own
TimeFormatPref. So with the app set to 24h under an English locale the
dial still showed AM/PM, while every time label (which reads
LocalUse24HourFormat) showed 24h.
Seed the picker from LocalUse24HourFormat — the app-wide clock
convention already resolved once at the root from TimeFormatPref — so the
dial matches the labels. Drops the now-unused deviceUses24HourClock
helper.
