fix(account): handle single-word names in OIDC and GitHub auth providers (#10631)

When a user's name has no spaces (common for CJK names like "西门吹雪"),
name.split(' ') returns a single-element array so the last name
destructures as undefined, causing a PostgreSQL NOT NULL constraint
violation on the last_name column.

- openid: prefer standard OIDC given_name/family_name claims when
  available, fall back to splitting name with safe slice(1).join()
- github: same split fix using displayName ?? username
- loginOrSignUpWithProvider: add ?? '' defensive fallback at insertOne
  to guard against any undefined last name reaching the DB

Fixes #10628
