support `redirect_after_login` query param on login/register screen

[ajbura]

Describe the problem

Currently if a link is shared to register a user, user need other link to follow in order to join any community.

Describe the solution you'd like

With redirect_after_login query param we will be able to register as well invite user in single link.

Alternative: currently only alternative is to feature/public-directory room on client/server and hope user to find them.

Hey @ajbura 👋 I’d like to work on this feature.

My plan is to add support for a redirect_after_login query parameter on the login/register screens. I’ll handle it by checking the query param (or storing it in sessionStorage if needed) and redirecting the user to that path right after successful login or registration.

If that approach sounds good, could you please assign this issue to me? I’d be happy to implement it.
