Child-profile business layer (Feature 03, task 1)
Business-layer functions over ChildrenDao for creating and editing child profiles, so the Feature 09 service gate never touches the DAO directly. - children.py: create_child (display name required and trimmed, whitespace-only rejected; duplicate display name allowed but logged as a warning, case-insensitive and whitespace-normalised on both sides), edit_child (_UNSET sentinel for leave-alone; returns the updated record; renaming onto a different child's name warns, own name does not), set_child_active (the only removal path), and list_children (display order). Explicit None for optional fields raises instead of silently no-oping: the DAO's update deliberately writes only provided fields and cannot express NULL, so a clear request must not masquerade as one. UTC second-precision stamps per the timestamp policy. - tests/test_children_registry.py: 27 tests covering the typed round-trips, name validation matrix, duplicate-name warning behaviour (create and rename, including the rename-to-self non-warning), partial edits, refusal of unsupported clears, deactivation round-trip and list ordering.
