refactor config validation to use provider registry

- use provider.GetProvider() for provider validation
- use provider.GetModel() for model validation
- use p.RequiresAPIKey() for API key checks
- warn for unrecognized language codes (don't error)
- add ValidateModelLanguageCompatibility for model-language checks
- remove hardcoded isValidLanguageCode function

- Close cleanup (TestElevenLabsStreamingAdapter_Close, TestOpenAIRealtimeAdapter_Close)
- `go test -race ./internal/transcriber/...` passes with no race conditions
- All tests passing, typecheck passes
### Task 41: Update config validation to use provider registry
- Refactored `internal/config/validate.go` to use provider registry
- Added `mapConfigProviderToRegistryName()` to map config names to registry names
- Added `envVarForProvider()` helper for error messages
- Provider validation now uses `provider.GetProvider()` instead of hardcoded switch
- Model validation now uses `provider.GetModel()` to verify model exists
- API key validation uses `p.RequiresAPIKey()` - local providers (whisper-cpp) skip this check
- Language validation: warns for unrecognized codes (log.Printf) but doesn't error
- Added `ValidateModelLanguageCompatibility(registryProvider, modelID, langCode)`:
- Returns nil for auto language ("")
- Checks `model.SupportsLanguage(langCode)`
- Returns error with model name, language, and truncated list of supported languages
- LLM validation also refactored to use registry
- Removed old hardcoded `isValidLanguageCode()` function
- Updated tests: replaced TestIsValidLanguageCode with TestValidateModelLanguageCompatibility
- All tests passing, typecheck passes
