App.tsx now fetches GET /api/hives/status (the swarm-controller
aggregate: one row per roster hive, freshness derived at read time
from the status bucket) instead of GET /api/hives + a static
'configured' chip. Renders fresh/stale/never_reported/unknown as
StatusChip tones with a relative age, per the placeholder comment that
was already waiting on this endpoint to exist.
Adds a small local fmtAgo helper (src/util.ts) mirroring the
dashboard package's near-identical formatter — not worth sharing
across a vanilla-JS and a Preact/TS call site.
