fix(remote): address PR review comments for remote management
- P1: Make broadcast_provider_switch async to avoid blocking_read panic - Changed from sync blocking_read() to async read().await - Updated all 4 callers (tray.rs, failover_switch.rs, failover.rs, provider.rs) - Wrapped async calls in tauri::async_runtime::spawn where needed - P2: Restart server on Tailscale toggle with UI feedback - Added restarting state with yellow pulse indicator - Server stops, waits for full shutdown, then restarts with new config - Validates server health after restart - P2: Restart server on port change while keeping enabled - Port changes now trigger full server restart instead of just disabling - Explicitly passes new port to start_remote_server command - Fixed checkServerStatus to use explicit port parameter instead of stale closure-captured settings.remotePort - start_remote_server now accepts explicit port/tailscale params - Removed dependency on get_settings() to avoid race conditions - Frontend passes configuration directly to the command - Added unit tests for RemoteSettings component and remote backend Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
