Jun-te Kim 18063a2d7f Fall back to nested has_hot_water_cylinder for full-SAP certs
A SAP-Schema-17.0 full-SAP cohort cert (8265-7433-3220-9736-7902) omits the
top-level `has_hot_water_cylinder` and lodges it only under `sap_heating`. The
required top-level field on SapSchema17_1 made `from_dict` raise and skip the
cert.

Fix: make the top-level field Optional, and have the full-SAP mapper
(`from_sap_schema_17_1`, also used by 17.0/18.0.0 via delegation) fall back to
`sap_heating.has_hot_water_cylinder`. RdSAP mappers are unchanged (they keep the
top-level required field; their SapHeating has no such attribute).

Cert now maps + calculates (sap 76). Regression tests for the nested true/false
fallback.
