fix(ext/popup): auto-popout for attachment types, keep login/note in popup

- Login and secure_note types stay in popup without attachment UI
- All other types (identity, card, key, totp, document) auto-redirect
  to full tab when selected
- Attachments only shown for login/secure_note when opened in tab
