Add opt-in hourly dashboard data updates

[Copilot]

Adds hourly dashboard data downloads behind an off-by-default browser setting. Updates pause on low battery, data-saver, metered, or cellular connections.

• Scheduling

  • Triggers hourly downloads through a service worker while the dashboard is open.
  • Caches allow-listed, same-origin dashboard data with network-first fallback.

• Safety

  • Canaries workers before activation.
  • Force-registers a cache-busted worker when the active worker becomes unhealthy.
  • Bounds install, activation, and download waits to prevent stuck updates.

• Settings

  • Adds a device-local checkbox to the Settings page.
  • Unregisters the worker and clears scheduling state when disabled.

• Packaging

  • Includes the worker and update coordinator in dashboard builds and package manifests.

Implemented in 3b17018. Opted-in dashboards now register hourly Periodic Background Sync where supported, with a PWA manifest, persisted safe data URLs, browser power-aware scheduling, metered-network guards, and foreground fallback.

@copilot review implementation and make sure this does not lead to some ghostly service worker because of a bug. Must handle offline gracefully and datatbade full.

Must cap database usage at 2Gb and start dropping older runs if needed.

Addressed in e17c258. Disabled settings now clear persisted schedules and discover/unregister stale dashboard workers; cross-tab changes fail closed. The worker serves previously cached app/data responses offline and treats cache-write failures as non-fatal. Canonical IndexedDB is capped at 2 GB with conservative headroom, exact usage checks where available, oldest-first run subtree eviction, bounded transaction history, and progressive quota recovery. Full repository checks, 861 unit tests, 69 browser tests, secret scanning, and CodeQL pass.

@copilot update dashboard aw.yml

Updated dashboard/aw.yml in 6022a7c to document the packaged optional background data updates. Verified the manifest includes all worker, update coordinator, quota, and retention runtime assets; focused package checks pass.

@copilot data updates must happen even if the page is not opened.

Implemented in 2b0262e. The setting now remains on only after Periodic Background Sync permission is granted and the registered tag is verified, so downloads continue through the service worker after the page closes. Unsupported, denied, or failed registrations turn the setting off and unregister cleanly instead of silently falling back to open-page-only updates.
