Surface when LibrePortal is behind upstream and let users update from the
WebUI, reusing the proven git-update path instead of reinventing it.
Detection (host): webuiSystemUpdateCheck writes
frontend/data/system/update_status.json from a throttled git fetch +
behind-count + VERSION compare, off the existing per-minute
`webui generate system` cron. A new /VERSION file is the canonical version.
Display (frontend): update-notifier.js/.css render a global topbar badge
(every page) and a dashboard banner (prominent when behind, subtle "up to
date" with a manual check otherwise), plus a details panel.
Actions go through the task pipeline:
- `libreportal update apply` -> webuiRunUpdate (non-interactive: guards,
forced check, gitPerformUpdate, then dockerInstallApp libreportal)
- `libreportal update check` -> forced recheck
gitFolderResetAndBackup's body is extracted into gitPerformUpdate (no exit)
so the WebUI path can reuse it; the interactive CLI flow is unchanged.
Detection JSON verified against the repo (up-to-date and behind cases).
webuiRunUpdate's re-clone + redeploy still needs validation on a live host.
The latest-version source is git for now and is the single swap point for
get.libreportal.org later — the JSON contract and frontend stay unchanged.
