feat(client): add Chinese verbose_name and help_text to all client fields (Phase 4.1 part 2/9)
Sync DATA_MODEL_CLIENT.md field-level Chinese annotations to Django
models across 11 client tables (Client, ClientContact, ClientRequirement,
ClientSchoolPreference, ClientFavoriteFolder, ClientFolderItem,
ClientFollowLog, ClientFollowLogAttachment, ClientViewing,
ClientPropertyMatch, ClientStatusLog).
Pre-existing docstrings retained on ClientFollowLog (partitioned parent
treated as unmanaged) and ClientStatusLog (immutable audit log).
