feat: A whole slew of things

- Use a md5 hash of the session cookie value as key for session validity check
- Introduce global state
- Introduce a common interface for form logic, and implement it on the sign-in form
- Introduce static resolve() on all services instead of new-upping all over.
- Implement /portal on the frontend to support giving the frontend a inital context from server or anywhere.
- Show a notification when users sign in for the first time after validating their email
