feat: add user profile editing functionality

- Implemented edit and update actions in UsersController
- Created edit user view and form partial
- Updated user model validation to allow nil password
- Modified header to link to user settings
- Added integration tests for successful and unsuccessful edits

This commit introduces the ability for users to edit their profile
information, including name and email. It also includes validation
updates to allow users to update their profiles without changing
their password. Integration tests ensure that both successful and
unsuccessful edit attempts are handled correctly.
