feat(android): integrate daily notification plugin with native fetcher

Add native Android components for daily notification plugin integration:
- TimeSafariApplication: Custom Application class to register native fetcher
- TimeSafariNativeFetcher: Implements NativeNotificationContentFetcher interface
- network_security_config.xml: Allow cleartext for local development

Configuration updates:
- AndroidManifest.xml: Link custom Application class, add required permissions
- build.gradle: Add Java 17 compile options and required dependencies
- capacitor.config.ts: Add DailyNotification plugin configuration
- NativeNotificationService.ts: Use "daily_" prefixed ID for schedule rollover

Note: Subsequent notification scheduling after first fire still has issues
that require further investigation.
