Issues fixed:
1. Added missing user_applesocialauth deletion (Sign in with Apple)
2. Added missing residence_residencesharecode deletion
3. Simplified user deletion to always use WHERE is_superuser = false
(GORM's Exec with IN clause and slice was unreliable)
The delete query now directly filters on is_superuser column instead of
using NOT IN with a precomputed list of IDs, which is both simpler and
guaranteed to preserve all superuser accounts.
