feat: Add DigestUpsertRequest and LockEntity models

- Introduced DigestUpsertRequest for handling digest upsert requests with properties like ChannelId, Recipient, DigestKey, Events, and CollectUntil.
- Created LockEntity to represent a lightweight distributed lock entry with properties such as Id, TenantId, Resource, Owner, ExpiresAt, and CreatedAt.

feat: Implement ILockRepository interface and LockRepository class

- Defined ILockRepository interface with methods for acquiring and releasing locks.
- Implemented LockRepository class with methods to try acquiring a lock and releasing it, using SQL for upsert operations.

feat: Add SurfaceManifestPointer record for manifest pointers

- Introduced SurfaceManifestPointer to represent a minimal pointer to a Surface.FS manifest associated with an image digest.

feat: Create PolicySimulationInputLock and related validation logic

- Added PolicySimulationInputLock record to describe policy simulation inputs and expected digests.
- Implemented validation logic for policy simulation inputs, including checks for digest drift and shadow mode requirements.

test: Add unit tests for ReplayVerificationService and ReplayVerifier

- Created ReplayVerificationServiceTests to validate the behavior of the ReplayVerificationService under various scenarios.
- Developed ReplayVerifierTests to ensure the correctness of the ReplayVerifier logic.

test: Implement PolicySimulationInputLockValidatorTests

- Added tests for PolicySimulationInputLockValidator to verify the validation logic against expected inputs and conditions.

chore: Add cosign key example and signing scripts

- Included a placeholder cosign key example for development purposes.
- Added a script for signing Signals artifacts using cosign with support for both v2 and v3.

chore: Create script for uploading evidence to the evidence locker

- Developed a script to upload evidence to the evidence locker, ensuring required environment variables are set.

 ## Decisions & Risks
  - LNM v1 fixtures staged (2025-11-22) and approved; hash recorded in `docs/modules/sbomservice/fixtures/lnm-v1/SHA256SUMS`. SBOM-SERVICE-21-001/002/003/004 are DONE.
- - DEVOPS-SBOM-23-001 delivered 2025-11-30 (Sprint 503) providing vetted offline feed + CI proof; SBOM-CONSOLE-23-001/002 now unblocked (status TODO) and should proceed to implementation.
+ - DEVOPS-SBOM-23-001 delivered 2025-11-30 (Sprint 503) providing vetted offline feed + CI proof; SBOM-CONSOLE-23-001 and SBOM-CONSOLE-23-002 are DONE (2025-12-03) using vetted feed + seeded data; storage-backed version still to follow.
+ - Console endpoints validated via tests; current implementation uses in-memory/catalog seeds—replace with Mongo-backed projections before release and update docs accordingly. Track storage wiring as follow-up (new task below).
 - Projection endpoint validated (400 without tenant, 200 with fixture data) via WebApplicationFactory; WAF configured with fixture path + in-memory component repo fallback.
 - `sbom.version.created` now emitted via in-memory publisher with `/internal/sbom/events` + backfill endpoint; production outbox/queue wiring still required before release.
 - Component lookup pagination now returns deterministic `nextCursor` for seeded data (fixed null cursor bug).
