feat: implement settings screen with reminders, biometrics, theme, and PDF export

- Daily reminder scheduling via flutter_local_notifications (inexact, repeating at chosen time) - Biometric lock gate on app launch with auto-prompt and manual unlock button - Theme mode selector (System/Light/Dark) persisted to settings DB - PDF export of full mood history shared via share_plus - Android: POST_NOTIFICATIONS, USE_BIOMETRIC permissions; switched to FlutterFragmentActivity
