* MQTT support
* feat(mqtt): redesign MQTT settings UI with improved UX
Restructure the MQTT settings page for clarity and usability:
UI Structure:
- Organize settings into logical sections (Auth, Home Assistant, Advanced)
- Use progressive disclosure for port (Auto/Custom) and base topic (Default/Custom)
- Move connection status badge into page header
- Conditionally show HDD debounce only when ATX extension is active
- Add inline validation for required broker field
Connection & Error Handling:
- Add test-then-save flow: Save & Reconnect validates connectivity before persisting
- Add standalone Test Connection button for dry-run validation
- Add testMqttConnection RPC with 5s timeout (no retry, no side effects)
- Surface friendly i18n-ready error messages for common failures (auth, timeout, TLS, DNS)
- Track last connection error on MQTTManager for status reporting
Copy:
- Rewrite all descriptions for clarity and brevity
- Use benefit-oriented, active-voice microcopy throughout
