Fix multiple production issues and add password change functionality

- Fixed frontend API URL configuration to use correct port 3002
- Fixed create event functionality by adding proper endpoint and fixing JSON parsing
- Fixed email settings save functionality by importing logActivity correctly
- Fixed admin settings save functionality by using api client instead of direct fetch
- Implemented password change functionality with modal and backend endpoint
- Added updated_at column to admin_users table
- Fixed all mock data issues - now using real backend data throughout
