feat(admin): support user profile editing, password resetting, and email column with search

- Add UpdateUser API and logics supporting nickname, email, admin flag modification, and password reset.
- Relocate user delete button and confirmation Alert into the EditUserModal.
- Optimize admin Switch change to trigger instant API request with rollback support.
- Fix missing email field in edit form initialization by fetching full profile metadata.
- Render email column in users list and support email-based filtering in UserFilterBar.
- Remove hardcoded styles and sizes from Switch components to follow global theme.
