Summary

Add batch dashboard tile hydration for the client and server.

Why

The dashboard should reduce request overhead by resolving queued tile hydration work in chunks while preserving the existing single-tile route as a fallback.

Changes

Adds POST /api/dashboard/tiles accepting { "tiles": DashboardTileReference[] }.
Returns { "state": "ready", "tiles": DashboardTileResolution[] }.
Resolves batch items through the same tile cache/coalescing path with server concurrency capped at 6.
Updates the client viewport hydration queue to send tile chunks of 6 to the batch endpoint.
Falls back to existing single-tile routes when batch hydration fails.
Adds router, route, concurrency, and client queue tests.

Testing

bun --filter @dimensionlab/web test -- src/server/index.test.ts src/server/routes/dashboard.test.ts src/lib/client/dashboard-refresh.test.ts src/App.test.tsx
bun --filter @dimensionlab/web check
bun install --frozen-lockfile
bun run check
bun run test

Notes

Existing /api/dashboard and /api/dashboard/tile/... routes remain compatible. No packages/ui changes.
