fix: gracefully degrade voice correction when agent connection is lost

Two bugs fixed:

1. recordingState stuck at .processing when no client is available:
   sendVoiceCorrectionRequest early-returned with voiceCorrectedText=rawTranscript
   but isVoiceCorrectionPending was never set true→false, so onChange never fired
   and the .processing UI (spinner hiding the input area) persisted forever.
   Fix: also reset recordingState = .idle in onChange(of: voiceCorrectedText),
   which fires in ALL code paths since voiceCorrectedText is always set.

2. Long hang when client exists but connection is lost (stale cachedClient):
   sendMessage triggered full auto-reconnect logic, keeping the user in
   .processing for up to ~30 s before eventually calling onComplete.
   Fix: check client.connectionState upfront in sendVoiceCorrectionRequest;
   if not .connected, fall back to raw transcript immediately without reconnect.
