feat(web-server): add /api/bar/summary aggregator with force-fresh

Single endpoint merging per-account quota, tier, paused, health and today cost
for the menu bar. Cached by default; ?refresh=true invalidates the quota cache
and pulls live server-side, debounced ~15s. Per-account errors degrade one row
without failing the payload; force-fresh skips paused accounts and caps fetch
concurrency.
