feat: implement splash screen with user preference toggle, update app branding with SafeBite logo across UI

- Add `splashScreenEnabled` preference to UserPreferences with default true
- Implement `SplashScreen` composable with animated logo, scale/fade transitions, and gradient background
- Add splash screen toggle in settings UI under "Interface" section
- Update navigation graph to conditionally show splash before dashboard when enabled
- Replace app launcher icons with SafeBite logo drawable
