feat(api): add provider creation endpoints and weight support
- Add `POST /admin/providers/preset` for streamlined creation of official providers (OpenAI, Anthropic, Gemini) - Add `POST /admin/providers/custom` for generic OpenAI-compatible providers - Add `weight` field to provider model and DTOs to enable weighted routing - Update sync service to propagate provider weights - Add unit tests for new creation handlers
