Replace the broken server-side OpenAI Whisper transcription with the browser-native Web Speech API. Changes: - Remove MediaRecorder-based audio capture and /api/speech-to-text call - Implement SpeechRecognition API for real-time transcription - Auto-detect browser support and hide button on unsupported browsers - Use continuous mode with interim results for better UX - Handle common errors (permission denied, no mic, network issues) - Automatically use browser locale for recognition language The original speech-to-text API endpoint was removed in the "Remove all legacy Blink v1 code" cleanup (c4200ec9) but the microphone button UI was kept, causing all transcription attempts to fail with 404. The Web Speech API is supported in Chrome, Edge, Safari (partial), and Firefox (behind flag). On unsupported browsers, the microphone button is now hidden rather than showing a broken feature.

Problem
The microphone button in the chat input was calling
/api/speech-to-textwhich no longer exists. The original API endpoint was removed in commit c4200ec9 ("Remove all legacy Blink v1 code") but the microphone button UI was kept, causing all transcription attempts to fail with "Speech transcription failed. Please try again."Solution
Instead of re-adding the server-side OpenAI Whisper integration, this PR uses the browser-native Web Speech API (
SpeechRecognition) which:Changes

On unsupported browsers, the microphone button is hidden rather than showing a broken feature.
