# Services CRUD operations
# NOTE: The orgid field is automatically populated by the backend layer:
#   - In .dspy files, orgid is obtained via `orgid = await get_userorgid()`
#   - The orgid is passed from .dspy to Python functions (create_service, delete_service, etc.)
#   - SQL templates use orgid for all WHERE clauses (data isolation by organization)
#   - orgid is EXCLUDED from UI: hidden in both list view (browserfields.exclouded)
#     and edit form (editexclouded), users never see or edit this field
#   - logined_userorgid param in CRUD definition enables framework-level org filtering
