Lets users create, edit, and complete tasks with no network connection, queued locally in IndexedDB and replayed via the existing /api/sync/ protocol once back online -- the same protocol the native Android app already uses, with zero backend changes. The service worker now routes the dashboard's offline fallback to a small client-rendered task app instead of the generic "you're offline" page; every other route keeps the generic fallback. Conflicts (server row touched elsewhere since last sync) auto-resolve as "local wins" rather than surfacing a resolution UI. Scope is title/ status/priority/due-date only -- tags, subtasks, time tracking, and recurrence editing offline are out of scope for this phase. Also adds the first real test coverage for sync/views.py (previously untested): new-item creation, soft-delete-bypasses-conflict-check, conflict detection/discarding, and both resolve_conflict paths.
