feat(dashboard): add cPanel-style server info bar and bump to v0.4.4

Adds a compact info strip at the top of the NixPanel dashboard showing
Username, Hostname, OS, NixPanel Version, Load Averages (live via
WebSocket), and Server Monitoring alert count. Alert count is derived
from GET /api/nixserver/services — green "All Clear" when all services
are running, amber "N Alerts" for any stopped/failed service.

Also fixes the version footer error state in Layout.tsx (versionError
→ "Version unavailable" fallback with retry button) so the spinner no
longer hangs indefinitely when the version API is unreachable.

+## [0.4.4] — 2026-04-11
+
+### New Features
+- **Server info bar on Dashboard** — cPanel/WHM-style info strip at the top of the NixPanel home page. Shows Username, Hostname, OS, NixPanel Version, Load Averages (live from WebSocket), and Server Monitoring alert count. Alerts are colour-coded: green "All Clear" when all managed services are running; amber "N Alerts" with a count of stopped/failed services.
+
+---
+
+## [0.4.3] — 2026-04-11
+
+### New Features
+- **Version display in sidebar** — the sidebar footer shows the currently installed version (e.g. `v0.4.3`), fetched live from the API. A green checkmark indicates up to date; an amber alert indicates an update is available.
+- **One-click panel upgrade** — "Upgrade panel" button in the sidebar footer. When a newer version is available it highlights amber and shows the target version. Clicking requires a confirmation step before running. Calls `POST /api/nixserver/system/upgrade` which fires `scripts/update.sh` in the background (git pull → npm install → prisma migrate → build frontends + server → restart service). The panel comes back online automatically after ~60 s.
+- **Check for updates button** — small refresh icon next to the version badge re-fetches version info on demand.
+- **Backend: `GET /api/nixserver/system/version`** — returns `currentVersion` (read from `/opt/nixpanel/package.json`), `latestVersion` (fetched from GitHub raw content with a 5 s timeout), and `updateAvailable` boolean.
+- **Backend: `POST /api/nixserver/system/upgrade`** — admin-only; responds immediately then spawns `scripts/update.sh` detached so the HTTP response is flushed before the service restarts.
