feat(login): new login flow (MIN-281)
Add new login flow - Design link
Flow: Login after authorization:
- For "user": close login modal
- For "curator/admin": show new dialog with options "Back to the map" and "Go to the admin panel"
For both users, the icon changes to "logged in"
Reopening login for logged-in user:
For "user":
- Switch account -> back to login
- Logout
For "curator/admin":
- Go to the admin panel
- Switch account -> back to login
- Logout
Additionally, the login button has been removed in the overlay drawer at Marek's request
