Keep query-bound dashboard elements responsive

[Copilot]

Dashboard queries could block or replace an entire page instead of updating their bound UI elements independently. This made pending states coarse-grained and undermined lazy rendering.

Changes

• Independent rendering

  • Keep fully query-bound pages mounted while worker queries resolve.
  • Publish results into reactive source bindings instead of replacing page DOM.
  • Preserve element-level skeletons and incremental updates.

• Lazy page chunks

  • Retain binding metadata in page stubs.
  • Load page structure before mounting query-bound elements.
  • Cancel stale preparation after navigation.

• Safe fallbacks

  • Retain page-level loading for mixed reactive/non-reactive views.
  • Keep section count sources page-bound.

• Coverage

  • Add regressions for binding isolation, chunk preparation, mixed pages, section counts, and cancellation.

Resolved the merge conflict with main in merge commit 02859bad. The resolution preserves query-bound source updates and the new render-performance instrumentation. Dashboard unit tests, lint, typecheck, build, focused Playwright tests, and CodeQL all pass.
