Store and handle more user attributes

[henrikskog]

• Stores all user attributes and not just email and studyYear
• Removes user fixtures because they are outdated and of little value now that users are stored in auth0
• Removes user dashboard page as this is recreated in next PR to avoid having 1 million changes in this PR

For how user data is stored in auth0 (some properties are stored in app_metadata and some in user_metadata, see:

monoweb/packages/core/src/modules/external/auth0-repository.ts

Line 17 in 7aced04

async update(sub: string, write: UserWrite) {

I have added a function that inserts fake data for the new fields until we gather this on signup such that we can maintain the not-null integrity of these fields thorughout the backend. See

monoweb/packages/auth/src/auth-options.ts

Line 77 in 7aced04

await core.syncedUserService.handlePopulateUserWithFakeData(token.sub, token.email) // Remove when we have real data
