🔧 Fix admin 'page not found' issue

- Fix LOGIN_REDIRECT_URL to redirect to /admin/ instead of homepage
- Create admin.py for agent_base to register BaseAgent model
- This ensures users stay in admin interface after login
- Admin will now show all agents and user management

Fixes the issue where admin login worked but redirected to homepage.
