US - Profil löschen - Githubissues

Value proposition

As a user i want to delete my account when I am not interested in using the app anymore.

[ ] User can choose "Account löschen" on the settings page
[ ] User account is deleted from database when user confirms to delete
[ ] User is logged out after confirming to delete and has to register again if he/she wants to sign in again

[ ] create branch US_deleteAccount
[ ] Add "Account löschen" button to the profile page
- [ ] When clicking it a modal opens- user is informed that his account will be deleted when confirming. user can abort or confirm
- [ ] When confirming send DELETE request to api/user including the user id
[ ] /api/user - create functionality for DELETE request - deleting the user account
[ ] Add placeholder information "gelöschte Person" etc. at all places we render user information by user id
