- Initialize isRegistering state from URL query parameter (mode=register)
- Update URL when toggling between login/register modes for shareable links
- Remove duplicate useRoute() calls in login/register handlers
- Ensures all Register buttons throughout the app show the registration form
This fixes the issue where Register links navigated to /login?mode=register
but the login page ignored the mode parameter and showed the login form instead.
