- Add GET /api/transcribe/status endpoint — returns whether any server transcription provider (Whisper/AWS/Local) is configured - Frontend checks status on login via checkTranscribeStatus() - When no provider configured: recording stops instantly, keeps live Web Speech API text, shows friendly toast — no error, no upload wait - Works in encounter, dictation, and SOAP tabs - App now works fully out-of-the-box with just an AI provider key
