feat: initialisation complète du CORE ProxmoxPanel

Backend Go 1.23+ :
- API REST + WebSocket (chi, gorilla/websocket)
- Authentification PAM via SSH + JWT RS256
- Chiffrement AES-256-GCM pour secrets SQLite
- Pool SSH, client Proxmox REST, hub WebSocket pub/sub
- Système de modules compilés à initialisation conditionnelle
- Audit log, migrations SQLite versionnées

Frontend Vue 3 + Vite + TypeScript :
- Thème Neumorphism sombre/clair (CSS custom properties)
- Wizard d'installation, Dashboard drag-drop, Terminal xterm.js
- Toutes les vues CORE + stubs modules optionnels
- i18n EN/FR (vue-i18n v11)

Infrastructure :
- Docker multi-stage (Go → alpine, Node → nginx)
- docker-compose.yml, .gitattributes, LICENSE MIT, README

+# Module — Services
+
+**Type**: Optional (disabled by default)
+
+Manage systemd services on the Proxmox host and LXC containers. Check status, start, stop, and restart services directly from the web interface.
+
+## Planned Features
+
+- List systemd services with current status (active/inactive/failed)
+- Start, stop, restart, reload actions
+- View service logs (last N lines via `journalctl -u <service>`)
+- Filter by status or name
+- LXC service management via `pct exec`
+
+## Planned API Endpoints
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| GET | `/api/services` | JWT | List services and their status |
+| POST | `/api/services/{name}/start` | JWT+Admin | Start a service |
+| POST | `/api/services/{name}/stop` | JWT+Admin | Stop a service |
+| POST | `/api/services/{name}/restart` | JWT+Admin | Restart a service |
+| POST | `/api/services/{name}/reload` | JWT+Admin | Reload a service |
+| GET | `/api/services/{name}/logs` | JWT | Last 100 log lines |
+
+Query parameter: `host=<optional>` to target a specific LXC.
+
+## How It Works
+
+Commands are executed over SSH using `systemctl`:
+
+```bash
+systemctl status nginx
+systemctl restart nginx
+journalctl -u nginx -n 100 --no-pager
+```
+
+For LXC containers:
+
+```bash
+pct exec <vmid> -- systemctl restart nginx
+```
+
+## Status
+
+> This module is currently a stub. The UI view is implemented (shows a "module not enabled" placeholder). Full implementation is planned for a future release.
+
+## Requirements
+
+- SSH access with sufficient privileges to run `systemctl` commands
+- `systemd` on the target host/containers
