fix: adjust and modify current passphrase pin logic

[guowei0105]

Summary by CodeRabbit

• Bug Fixes
  • Improved reliability when attaching a passphrase to a PIN by adding an extra verification step before showing success. This prevents rare cases of false success messages.
  • Ensures users receive accurate confirmation of a successful setup, with device lock behavior remaining consistent after completion.
  • Enhances overall feedback consistency during the passphrase-to-PIN attachment flow.
