Zentao #24/#25: commit 50f8581 added friend_request_verification and group_invite_verification to userPrivacyByUID, but existing databases lack those columns, so GetPrivacy failed with Error 1054 and every cross-user profile/qrcodes/friend-request endpoint returned 500.
Add user_privacy_schema.go which, under GET_LOCK, checks information_schema and ALTERs in any missing privacy columns, wired into the root adapter Open() and per-tenant TenantAdapterFor so tenant-scoped databases are provisioned too.
