fix(android): resolve Kotlin compilation errors

- Fix DeepLinkSheet import: com.clawdbot → bot.molt
- Remove duplicate helper functions from NodeGatewaySync.kt
- Make shared helpers internal in NodeRuntime.kt
- Rename a2ui constants to uppercase (A2UI_READY_CHECK_JS, A2UI_RESET_JS)
- Add missing padding/size imports in SettingsSheet.kt
- Update EncryptedSharedPreferences to use MasterKey API
