feat: Implement ScannerSurfaceSecretConfigurator for web service options

- Added ScannerSurfaceSecretConfigurator to configure ScannerWebServiceOptions using surface secrets.
- Integrated ISurfaceSecretProvider to fetch and apply secrets for artifact store configuration.
- Enhanced logging for secret retrieval and application processes.

feat: Implement ScannerStorageSurfaceSecretConfigurator for worker options

- Introduced ScannerStorageSurfaceSecretConfigurator to configure ScannerStorageOptions with surface secrets.
- Utilized ISurfaceSecretProvider to retrieve and apply secrets for object store settings.
- Improved logging for secret handling and configuration.

feat: Create SurfaceManifestPublisher for publishing surface manifests

- Developed SurfaceManifestPublisher to handle the creation and storage of surface manifests.
- Implemented methods for serializing manifest documents and storing payloads in the object store.
- Added dual write functionality for mirror storage of manifests.

feat: Add SurfaceManifestStageExecutor for processing scan stages

- Created SurfaceManifestStageExecutor to execute the manifest publishing stage in scan jobs.
