- Fix OAuth redirect to localhost by adding queryParams to Google sign-in
- Improve input text visibility in complete-profile page:
  - Remove backdrop-blur and semi-transparent backgrounds
  - Change text color from gray-900 to black with font-medium
  - Fix username validation styling (remove opacity from success/error states)
- Ensure OAuth flow works correctly for local development
- Maintain production OAuth functionality
