Improve user experience by eliminating full page reload after profile updates

[coderabbitai]

Issue Description

The profile page currently uses window.location.reload() to refresh profile data after successful updates, which provides a suboptimal user experience due to the full page reload. This approach is less efficient and disrupts the user's interaction flow.

Current Behavior

• After updating profile information, the page performs a full reload to display updated data
• This causes a brief loading state and interrupts the user's workflow

Expected Improvement

The profile data should update seamlessly without requiring a full page reload, either by:

• Updating local state directly with server response data
• Re-fetching only the profile data
• Exposing a refresh function in the useAuth hook

Context

This issue was identified during code review of the profile page implementation.
