feat: dark mode background fixes, chat bubble long-press menu, notification dedup, biometric auth for clear

- Fix: dark mode white backgrounds via transparent windowBackground, decorView color, and explicit Surface backgrounds on IoT/Profile/MainScreen
- Fix: dark mode text colors in ProfileScreen (nickname, account info, assistant status)
- Feat: long-press chat bubble to copy message text via DropdownMenu
- Feat: notification deduplication — track notified message IDs, clear on foreground
- Feat: cancel all notifications when app enters foreground
- Feat: biometric/device-credential verification before clearing local messages
