DomainDig v4.1.0: Add a full local data reset flow in Data Management

- add a destructive Delete All Data action with confirmation, progress, success,
  and failure handling
- centralize wipe behavior in DataResetService instead of scattering delete
  logic in views
- clear local persistence, temp/export files, integration secrets,
  notifications, caches, and in-memory app state
- reset sync, purchase, and integration services after wipe so the app returns
  to a clean first-launch state

Polish batch and empty-state UX

- present the batch sweep summary after manual bulk searches complete, not only
  from Watchlist
- align the Workflows empty state styling with other empty states by removing
  the extra background card treatment

Bump the project version from 4.0.0 to 4.1.0
