chore: update styles, add splash config, and improve search functionality

- Replace deprecated StyleSheet.absoluteFillObject with StyleSheet.absoluteFill (React Native 0.76+)
- Add splash screen configuration in app.json
- Fix duplicate UIBackgroundModes and add audio mode for iOS
- Disable Android ripple effect on tab bar buttons
- Improve SmartImage loading state to prevent unnecessary re-renders
- Refactor ImageGrid to use mainUri with separate previewUrl for better preview handling
- Add market search support with trade items tab in SearchScreen
- Pass homeTab prop to SearchScreen for context-aware search behavior
- Simplify fetchUnreadCount return type to void in MessageSyncService
- Fix StatusBar import from expo to react-native in ChatScreen
