Summary

Adds a client-side dashboard tile hydration scheduler with bounded concurrency, priority ordering, and per-tile failure backoff.

Why

Independent tile hydration should avoid launching every live datasource request at once, while still keeping important dashboard state fresh first.

Changes

Hydrate dashboard tiles through a queue capped at 6 concurrent requests.
Prioritize status, telemetry, modules, then services while preserving source document order inside each group.
Add per-tile backoff for failed tile hydration: 15s, 30s, 60s, then 120s max.
Reset tile backoff after successful hydration.
Add unit coverage for queue concurrency, backoff timing, priority order, and document-order preservation.

Testing

bun run check
bun run test
Independent review: no blocking findings after order-preservation coverage was added.

Notes

packages/ui is untouched.
Component-level backoff integration is covered through the scheduler/backoff helpers rather than a browser DOM harness.
