feat: display actual reminder schedule from server config (#386)

- Expose REMINDER_HOUR and REMINDER_MINUTES_BEFORE env values via settings API
- Add reminderHour and reminderMinutesBefore to frontend Settings interface
- Replace hardcoded i18n strings with parameterized translations
- Settings page now shows configured schedule instead of static 6:00 / 15 min
