Replace Calendula's app-local reminder-override plumbing with floret-kit's
core-reminders, shared with Agendula:
- CalendarReminderOverride (Inherit/None/Minutes) -> kit ReminderOverride, with
the kit's applyReminderOverride() map extension.
- The hand-rolled parse/serialize of the per-calendar override string -> kit
ReminderOverrideCodec, configured with Calendula's on-disk dialect
(id=minutes entries joined by ;, "none" sentinel). Format is unchanged, so
stored prefs round-trip identically (SettingsPrefsTest still green).
- ReminderUnit enum + the custom-amount decomposition (decomposeReminder) ->
kit ReminderUnit + decomposeReminderMinutes/ReminderAmount.
App-specific glue stays put: resolveDefaultReminder (timed vs all-day),
reminderLeadTimeLabel / reminderUnitLabel (app string resources), and the
global-default picker helpers.
Compile + unit tests green.
