Claude compatibility and model access restored

This urgent correction restored requests after the previous update and synchronized the available-model view in the API and Telegram bot.

Fixed issues

• POST /v1/chat/completions works again for Claude-compatible clients.
• Compatible route selection for that request was corrected.
• Fable 5 models are visible again in the catalog and GET /v1/models when they are available to the specific key.
• The API and bot now show the same set of available models.

Compatibility and next steps

No SDK, base URL, or API key change is required. Check GET /v1/models for your key, then retry the usual client request.
