Connectors: Sort providers alphabetically and scope settings to AI type.

Addresses review feedback:
- Reorder default providers alphabetically (Anthropic, Google, OpenAI).
- Sort all registered providers with `ksort()` for neutral ordering.
- Add `ai_provider` type check in settings registration to prevent
  AI-specific sanitize/description logic from applying to other types.
