feat(web): status page and home regrouped around tasks, inbox and plan (FE-1)

Status page reads /system/health and history: level banner, process table,
event-loop lag and SSE charts (monochrome recharts), database, engine,
schedules, disks with thresholds and mount roots. Home now shows in-progress
tasks, items needing attention, media overview, a plan strip with quick
toggles, recent finished/failed tasks, cache and retention, source health
with site account status, and a run-status summary.
