Replace the click-to-scan-only flow with a self-throttled auto-scan that
rides the existing task-processor idle poll (the same shape as the
network-drift check — no new daemon, unit, or endpoint):
- 'libreportal updater check auto' gates on the age of the generated
updates.json vs CFG_UPDATER_SCAN_INTERVAL (minutes, default 30,
0 disables); a fresh file makes the 60s tick a single stat() + return.
Manual checks and post-update rescans reset the clock for free, and a
missing file means the first scan runs ~a minute after install.
- Eligible signed hotfixes keep flowing through artifactApplyAuto, which
only enqueues ordinary tasks — mutations stay on the task path.
- Open updater surfaces (standalone /updater and the fleet Overview's
headless UpdaterPage) follow along with a 60s static-JSON re-read that
repaints only when a generated_at stamp changed; timer released via
dispose() on unmount, ticks skipped while hidden.
- Empty states now say the first scan happens automatically; Check now
stays as the immediate manual override.
