feat: initial wiki API server with account management

- HTTP API with JSON over configurable port (default 8080)
- Endpoints: POST /register, POST /login, POST /refresh, GET /health
- MariaDB storage with SHA-256 hashed credentials and tokens
- Token rotation on login and refresh
- Config loaded from config.json (not tracked in git)
- Graceful shutdown on SIGINT/SIGTERM
- Connection pool (25 max open, 10 idle, 5min max lifetime)
