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.
- Integrated with SurfaceManifestPublisher to publish manifests based on collected payloads.
- Enhanced logging for job processing and manifest storage.

feat: Define SurfaceManifest models for manifest structure

- Established SurfaceManifestDocument, SurfaceManifestSource, SurfaceManifestArtifact, and SurfaceManifestStorage records.
- Implemented serialization attributes for JSON handling of manifest models.

feat: Implement CasAccessSecret and SurfaceSecretParser for secret handling

- Created CasAccessSecret record to represent surface access secrets.
- Developed SurfaceSecretParser to parse and validate surface secrets from JSON payloads.

test: Add unit tests for CasAccessSecretParser

- Implemented tests for parsing CasAccessSecret from JSON payloads and metadata fallbacks.
- Verified expected values and behavior for secret parsing logic.

test: Add unit tests for ScannerSurfaceSecretConfigurator

- Created tests for ScannerSurfaceSecretConfigurator to ensure correct application of surface secrets to web service options.
- Validated artifact store settings after configuration.

test: Add unit tests for ScannerStorageSurfaceSecretConfigurator

- Implemented tests for ScannerStorageSurfaceSecretConfigurator to verify correct application of surface secrets to storage options.
- Ensured accurate configuration of object store settings.
