Implement Password Change Functionality

[Michael-Obele]

Currently, users are unable to change their account passwords. To enhance user security and control, implement a feature allowing users to change their passwords.

Acceptance Criteria:

• A dedicated "Change Password" option is available within the user's profile settings.
• Users must provide their current password for verification before changing it.
• The new password must meet specified complexity requirements (e.g., minimum length, character types).
• A confirmation page or message should be displayed after successful password change.
• Error handling for invalid passwords or password mismatches should be implemented.

By implementing this feature, users will have greater control over their account security and be able to proactively protect their information.
