Verify screen: Done button is the single commit action

Done button now handles everything in one tap:
- 'Confirm: delete N from phone + remove N from staging' — red button
- 'Confirm: delete N files from phone' — red button
- 'Confirm: remove N from staging' — red button
- 'Done — Back to Start' — normal blue (nothing to commit)

Deletes phone files (if delete-after-verify + checkboxes), removes
soft-removed files from staging, then navigates home.

Removed separate 'Delete N files' button — one action is clearer.
