feat: Implement user profile and parent profile button tests

- Added tests for user profile editing, including name changes, image uploads, and password changes.
- Implemented tests for changing the parent PIN with verification code handling.
- Created tests for account deletion with confirmation dialog and email validation.
- Introduced parent profile button tests for both temporary and permanent modes, verifying badge visibility and menu options.
- Updated Playwright configuration to include new test buckets for user profile and parent profile button scenarios.
- Added e2e plans documentation for user profile and parent profile button tests.
