test: add unit tests for app workers

[phoenix-server]

Summary

The app-level workers have very low or zero coverage. static-mirroring-worker.ts has 0% coverage entirely.

Files to cover

• src/app/static-mirroring-worker.ts (0%)
• src/app/app.ts (20% statements, 0% branches)
• src/app/worker.ts (52% statements, 9% branches)
• src/app/maintenance-worker.ts (43% statements, 13% branches)

Out of scope

• src/services/maintenance-service.ts — already at 100%
• src/services/payments-service.ts — covered by test: add unit tests for MaintenanceWorker and PaymentsService #440
• All files outside src/app/

Acceptance criteria

• Each worker has a corresponding .spec.ts under test/unit/app/
• Worker lifecycle (start, stop, error handling) covered
• Dependencies stubbed (DB, Redis, services)
• npm run cover:unit passes without regressions
