Consume two newly extracted floret-kit modules and drop the in-app copies:
- core-reminders: ReminderUnit / decomposeReminderMinutes, the ReminderOverride
model and the override codec. SettingsPrefs keeps its own DataStore wiring and
Agendula's ':' codec dialect; ReminderFormatting/ReminderLeadPicker keep the
app's R.string labels and presets.
- core-locale: AppLanguage. Deleted the app copy; SettingsScreen now passes
R.xml.locales_config to supportedTags().
Bumps the floret-kit submodule to include both modules.
