fix: Use 127.0.0.1 for OAuth per RFC 8252 and improve reliability

- Updated OAuth URLs from localhost to 127.0.0.1 (RFC 8252 requirement)
- Changed login page to use window.location.href for proper server redirects
- Added client-metadata.json for ATproto OAuth compliance
- Improved Step 2 theme test to check overall theme instead of specific details
