Delete all clears tasks and habits

One archive, one cleanup action

Delete all in Home's Archived section now clears completed or archived tasks and archived habits together. The confirmation gives exact task and habit counts before anything permanent happens.

Active and protected work stays safe

Tasks restored on another device while the confirmation is open are left alone. Active items, habits outside the visible feature, and another owner's habits are never included. Required historical records remain protected.

The complete path is regression tested

Release checks now cover mixed and habit-only archives, cancellation, stale records, offline task durability, partial server failures, request timeouts, ownership, protected-history fences, and the busy state that prevents duplicate deletion batches.

Dawn stays Dawn

Browser tabs, Home Screen installs, notifications, social previews, app headers, and native iOS artwork once again use Dawn's electric-blue arc and gold sun. Release checks now reject archived Blackout icon paths and fingerprints anywhere in the active Dawn identity chain.
