Add unit tests and implementations for MongoDB index models and OpenAPI metadata
- Implemented `MongoIndexModelTests` to verify index models for various stores. - Created `OpenApiMetadataFactory` with methods to generate OpenAPI metadata. - Added tests for `OpenApiMetadataFactory` to ensure expected defaults and URL overrides. - Introduced `ObserverSurfaceSecrets` and `WebhookSurfaceSecrets` for managing secrets. - Developed `RuntimeSurfaceFsClient` and `WebhookSurfaceFsClient` for manifest retrieval. - Added dependency injection tests for `SurfaceEnvironmentRegistration` in both Observer and Webhook contexts. - Implemented tests for secret resolution in `ObserverSurfaceSecretsTests` and `WebhookSurfaceSecretsTests`. - Created `EnsureLinkNotMergeCollectionsMigrationTests` to validate MongoDB migration logic. - Added project files for MongoDB tests and NuGet package mirroring.
