[BUG] First and Last name must be set on setup with OAuth

The bug

Hello. So i've set up immich on docker with additional custom proxy on top of immich's proxy and with OAuth service (Keycloak). I made a user in Keycloak but didn't specify the First and Last name. As soon as i hit Login with OAuth immich throws this error:

(user.firstName[0] + user.lastName[0]).toUpperCase is not a function - 500
TypeError: (user.firstName[0] + user.lastName[0]).toUpperCase is not a function

Reproduction steps

1. Set up Immich 1.60.0 with custom proxy (Traefik) on top of it
2. Deploy Keycloak 21
3. Configure both Keycloak and Immich to work together
4. In Keycloak, add user to Immich realm with entering just username, email and password
5. Logout from Immich and click Login with OAuth
6. Enter the correct credentials that you created with user in Keycloak
7. See the error
