feat: complete Git Repo Manager MVP implementation

Backend (Phase 1-6):
- Pydantic schemas for request/response validation
- Service layer (SSH Key, Server, Repo, Sync)
- API routes with authentication
- FastAPI main application with lifespan management
- ORM models (SshKey, Server, Repo, SyncLog)

Frontend (Phase 7):
- Vue 3 + Element Plus + Pinia + Vue Router
- API client with Axios and interceptors
- State management stores
- All page components (Dashboard, Servers, Repos, SyncLogs, SshKeys, Settings)

Deployment (Phase 8):
- README with quick start guide
- Startup script (start.sh)
