- Updated `transcriber.go` factory to use consolidated OpenAI adapter for groq-transcription and mistral-transcription
- Both now use `NewOpenAIAdapter` with their respective endpoints
- All tests passing, typecheck passes
### Task 14: Update ElevenLabs BatchAdapter to use EndpointConfig
- Refactored `internal/transcriber/adapter_elevenlabs.go` to use EndpointConfig
- New constructor: `NewElevenLabsAdapter(endpoint *EndpointConfig, apiKey, model, lang string)`
- Uses `endpoint.BaseURL + endpoint.Path` for URL (no hardcoded URL)
- Language converted via `language.ToProviderFormat(a.language, "elevenlabs")`
- Kept `xi-api-key` header for ElevenLabs-specific auth
- Added `NewElevenLabsAdapterFromConfig` for backward compatibility
- Updated factory to use `NewElevenLabsAdapterFromConfig`
- Updated tests for new constructor signature
- All tests passing, typecheck passes
