docs: cover per-app language and exact-minute time entry

Sweep of the 2026.07.05 and 2026.07.02 releases found two features the
reference docs omitted:
- languages.md said there's no in-app language setting, but Android 13+ has
  a system per-app language picker (KashCal advertises all 67 locales to it).
- event-form.md didn't mention the time picker's keyboard button for typing
  an exact minute instead of snapping to the 5-minute wheel.

+On **Android 13 and newer**, you can also give KashCal its own language, separate from

+Language). Pick a language there and KashCal uses it regardless of your device language.
 
 If KashCal doesn't yet have your exact regional variant, it falls back to the
 closest available language, and ultimately to English.
