feat: implement robust multi-tier text input architecture and ADB diagnostics

- Android Text Input & IME Normalization:
  - Implement progressive 3-tier input architecture in AndroidAdbDriver and AndroidDeviceController:
    - Tier 1 (Primary): Zero-dependency clipboard injection + KEYCODE_PASTE (immune to IME Pinyin interception, full Unicode/Emoji support, preserves multiline formatting).
    - Tier 2 (Broadcast): Base64 broadcast injection when ADBKeyboard is active.
    - Tier 3 (Fallback): Native ADB physical keyevent fallback.
  - Add literal newline normalization (\r\n, \n, \r) to prevent JSON escape string corruption (e.g. '10086\n' -> '10086、n').
  - Add set_clipboard method to UIAutomatorClient without auxiliary APK requirements.

- Diagnostics & System Probes:
  - Add adb_keys diagnostics probe for ADB key auth checks.
  - Integrate diagnostics into CLI doctor command.

- Admin Console & Showcase UI:
  - Improve model service and system router in admin console.
  - Enhance workspace stream view and session state in showcase UI.
