Add test coverage for the deep readiness probe degraded and paused branches

[mikewheeleer]

Test the deep health probe degraded and paused states

Description

GET /api/v1/health/deep in src/index.ts returns status: "ok", "degraded" (503), or "paused" based on runHealthChecks() and the paused flag, and it reports checks[], uptime, memory, pid, and node. Only the happy ok path is covered today; the degraded 503 branch (a failing check) and the paused 200 branch are untested, as is the per-check { name, status, durationMs } shape. This issue adds coverage for all three states.

Requirements and context

• Repository scope: StableRoute-Org/Stableroute-backend only.
• Assert the ok path returns 200 with both storage and clock checks present and status: "ok".
• Force the degraded branch (e.g. by stubbing pairMeta/storage so the storage check fails, or by injecting a failing check) and assert a 503 with status: "degraded".
• Toggle pause via POST /api/v1/admin/pause, assert GET /api/v1/health/deep returns 200 with status: "paused", then unpause to restore state.
• Assert the response carries uptimeSeconds, memory.rssMb, memory.heapUsedMb, pid, and node.

Suggested execution

• Fork the repo and create a branch
• git checkout -b test/health-33-deep-probe-branches
• Implement changes
  • Write comprehensive tests in: create src/__tests__/healthDeep.test.ts.
  • Add documentation: none beyond test names.
  • Restore any stubbed globals and the pause flag in afterEach to avoid cross-test bleed.
  • Validate security: confirm the probe body exposes no secrets.
• Test and commit

Test and commit

• Run npm run build, npm run lint, and npm test.
• Cover edge cases: ok, degraded (503), paused (200), all check fields present.
• Paste the full npm test output and a coverage summary in the PR.
