fix: skip password confirmation for OAuth users

OAuth users don't have passwords set, so they should not be prompted for password confirmation when performing destructive actions. This fix:
- Detects OAuth users via the hasPassword() method
- Skips password confirmation in modal for OAuth users
- Keeps text name confirmation as the final step
- Centralizes logic in helper functions for maintainability
- Changes button text to "Confirm" when password step is skipped

Fixes #4457
