Subject: [PATCH] fix(version): cache-bust refresh + clear stale state on
 manual check, bump to v0.4.5

The refresh/retry button called fetchVersion() without clearing
versionInfo first, so the old value stayed displayed with no feedback.
On manual refresh it now immediately sets versionInfo to null (shows
spinner) then fetches with ?_t=Date.now() to bypass any browser cache
of the API response.

Bump version to 0.4.5 to include all fixes since 0.4.4 (day/night
toggle, uptime/kill allowlist, auto-retry on version error).

+
+### Bug Fixes
+- **Sidebar version refresh not updating** — clicking the refresh icon now clears the stale version immediately (shows spinner) and adds a `?_t=` cache-bust parameter so the browser never serves a cached response. Same fix applied to the "Retry" button in the error state.
+- **`uptime` and `kill` missing from exec allowlist** — caused `GET /api/nixserver/system/info` to throw "Command not allowed", returning 500 and leaving Hostname/OS as `…` on the dashboard.
+- **Version fetch auto-retry** — when the version API fails (e.g. during service restart after upgrade), the sidebar now automatically retries every 5 s until it succeeds instead of permanently showing "Version unavailable".
+
+### New Features
+- **Day/Night mode toggle** — sun/moon flip switch at the right end of the dashboard info bar. Light palette: page `#f0f4f8`, cards `#ffffff`. Preference persisted to `localStorage`. All pages switch via seven `[data-theme="light"]` CSS overrides in `index.css` without touching individual page files.
