Add Whisper voice transcription to Telegram bot

- handleVoice() downloads Telegram audio and transcribes via Whisper API - transcribeAudio() calls Whisper with Basic Auth, handles json response - TelegramWebhookController now routes message.voice and message.audio - Whisper URL, token and toggle configurable from admin config panel - Transcribed text echoed back to user then processed as normal text intent Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
