Add internal admin claims APIs and review UI

[GsCommand]

Motivation

• Provide an operator-facing view to review persisted CommandLayer namespace claim requests stored in Neon/Postgres.
• Allow listing and inspecting individual claim requests, associated agents, and event timelines for manual review.
• Keep admin access gated by a simple environment-protected API key until a proper auth system is added.

Description

• Added an admin auth helper api/admin/_auth.js that enforces ADMIN_API_KEY with Authorization: Bearer <key> and returns 503 ADMIN_NOT_CONFIGURED when unset or 401 UNAUTHORIZED when invalid.
• Added GET /api/admin/claims in api/admin/claims.js to return newest-first claims from claim_requests (default limit=50, capped to 200) and compute agentCount from claim_agents.
• Added GET /api/admin/claim?claimId=... in api/admin/claim.js to return the claim row, its agents, and claim events for detailed inspection.
• Added a lightweight internal review page public/admin/claims.html with API key storage (session/localStorage), claims table, clickable rows, detail panel, and copy buttons for claim JSON and ENS records; all server APIs use lib/db.js for DB access.
• Added tests in tests/api-admin-claims.test.js to validate admin config/auth behavior and mocked DB responses for list/detail endpoints.

Testing

• Ran npm test at repo root and all tests passed (66 tests passed, 0 failed), including the new admin tests.
• Verified the example checks with cd examples/webhook-auto-verify && npm run check which completed successfully.
• npm install at the repo root failed in this environment due to a registry 403 when attempting to fetch @neondatabase/serverless.
• npm run build is not present in the repo (missing build script), so no build step was executed.
