Subject: test(backend): add unit tests for admin handlers and taskqueue

Add comprehensive tests for previously untested packages:
- admin: middleware auth checks, CRUD handlers for users/games/problems/testcases
- taskqueue: task creation, payload serialization, code hash calculation
- api: expose SetUserInContext helper for cross-package test support
