User registration flow

[myrddral]

• [x] implement sign up form component
• [x] add reusable Form wrapper with react-hook-form
• [x] define schemas for User entity and sign up form validation
• [x] implement client side validation of form fields + error display
• [x] implement server side validation of form data within server action
• [x] extend next-auth with handling API communication and token business for signing up
• [ ] set up mailing for user account confirmation
• [ ] implement subpage for handling one time sign in URL and result messages -> it has to be verified with the backend API

@mankamolnar This part will require some enhancement on the backend auth API routes:

• [ ] JWT & refresh token issuance
• [x] return some persisted user data (id, name, email, role) to be stored in session
• [x] error handling: we need uniform response structure with correct statuscodes and defined error codes, this is essential for proper internalization and centralized error handling + logging
