test(dashboard): Phase 5 P1 — auth/csrf/health/orchestrator tests + coverage gate

Closes the Phase 5 P1 testing checkbox. Adds 35 new unit tests across the
modules called out in the roadmap and wires a v8 coverage gate into CI.

Coverage of newly-tested files (lines / branches):
  lib/auth.ts                          94.4% / 100%
  lib/csrf.ts                          95.1% /  90%
  modules/health/repository.ts          100% /  92%
  modules/deployments/orchestrator.ts  95.2% /  74%
  modules/services/repository.ts        100% / 100%
  modules/hermes-ops/repository.ts     95.2% /  68%

Threshold (lines/funcs/stmts ≥85%, branches ≥65%) is scoped to those six
files via `coverage.include` so untested legacy modules (vm, system,
audit, route handlers) report but don't gate. Add files there as they
gain real tests — ratchet up, never relax.

Test approach mirrors the existing services/hermes-ops suites: hoisted
mocks for I/O (fetch, child_process, fs/promises, cosmos-init), real
JOSE-signed JWTs for the auth path, fake timers for cache TTL and CSRF
expiry assertions.

 - [x] **P0:** Fix the CI workspace path (`${{ gitea.workspace }}`) in `.gitea/workflows/ci.yml`, `DEPLOYMENT.md`, `scripts/deploy-hotcopy.sh` (currently point at non-existent `/opt/bytelyst/bytelyst-devops-tools/...`).
 - [x] **P0:** Replace the no-op `lint` echo with real linting (`next lint` for web, minimal ESLint for backend); make `pnpm lint` fail on bad code.
-- [ ] **P1:** Add tests for `auth`, `csrf`, `deployments/orchestrator`, `health`, **and `hermes-ops`**; add `pnpm test:coverage` gate.
+- [x] **P1:** Add tests for `auth`, `csrf`, `deployments/orchestrator`, `health`, **and `hermes-ops`**; add `pnpm test:coverage` gate. *(35 new unit tests; v8 coverage thresholds gated on the six tested files in `backend/vitest.config.ts` (≥85% lines/funcs/stmts, ≥65% branches), wired into Gitea CI as a dedicated step. Today's actuals: ≥95% lines on every gated file. Ratchet up as more modules get tested.)*
 - [ ] **P1:** Resolve the SSE TODO — either ship a Fastify-5-compatible log-stream or remove the SSE claim from docs/UI.
 - [ ] **P1:** Fix doc drift (web port 3000 vs 3049; endpoint URLs; merge duplicate deployment docs).
 - [ ] **P1:** Document the docker-socket + host-log/script mount privilege surface (the backend reads cross-user/host paths — blast radius must be written down; consider an allow-list wrapper over the raw socket).
