hermes - 💡(How to fix) Fix Login redirect hardcoded to /dashboard breaks custom dashboard routes

Bug Description

After a user logs in, the auth flow always redirects to /dashboard, regardless of what route the user intended to access or what the actual dashboard route is configured to be.

This breaks deployments where the main dashboard is mounted on a different path (e.g. /kanban). Users end up on a 404 page immediately after login.

Steps to Reproduce

1. Configure a custom dashboard route (e.g. Kanban UI on /kanban).
2. Navigate to /kanban while logged out.
3. Get redirected to /login.
4. Log in with valid credentials.
5. Observe redirect to /dashboard (404) instead of /kanban.

Expected Behavior

The login flow should either:

• Respect a ?next= (or equivalent) query parameter to return the user to their originally requested route, OR
• Allow the post-login destination to be configurable rather than hardcoded to /dashboard.

Actual Behavior

User is unconditionally redirected to /dashboard after successful authentication.

Environment
