feat: enhance DoH profile management and resolver policy in modules

- Added `DohResolverPolicy` schema to OpenAPI documentation, defining policies for domain resolution.
- Updated module handling to support multiple DoH profiles via `doh_profile_ids` and introduced `doh_resolver_policy` in the API.
- Refactored related functions to accommodate the new DoH profile structure, ensuring backward compatibility with existing `doh_profile_id`.
- Enhanced UI components to allow selection and management of DoH profiles and policies in the web interface.
- Updated database interactions to handle new fields and ensure proper data normalization.
