Implement missing REST API endpoints that the web-admin frontend
pages were calling but had no backend support:
- GET/POST/PUT /api/v1/agent-config (engine, prompt, turns, budget, tools)
- GET/POST/PUT/DELETE /api/v1/agent/skills (CRUD for agent skills)
- GET/POST/PUT/DELETE /api/v1/agent/hooks (CRUD for hook scripts)
Each endpoint includes entity, repository, service, and controller
layers following the existing DDD + tenant-aware patterns.
