Jun-te Kim 6d98ecf375 Tolerate non-string building-part identifier (fix TypeError) ... A SAP-16.x cohort cert (9258-4062-7265-2844-7954) lodges a bare int building- part identifier (the second part as `1` after "Main Dwelling"). `BuildingPartIdentifier.from_api_string` regex-matched it assuming a string and raised "TypeError: expected string or bytes-like object, got 'int'", failing the whole property. Fix: guard the match on `isinstance(api_identifier, str)` so a non-string identifier falls to OTHER, matching the documented "anything unrecognised -> OTHER" contract. The baseline SAP fabric sums all building parts regardless of identifier, so OTHER is SAP-neutral; the identifier only labels parts for measure targeting. Fixes every mapper (all route through from_api_string). Cert now maps + calculates (sap 63). Regression test added.
