Khalim Conn-Kowlessar ff36014e6f Map PasHub window glazing_type labels to SAP10 cascade codes
`_map_sap_window` copied the raw `glazing_type` survey label; the
calculator's isinstance-int guards read it as non-int and fell to the
double-pre-2002 U=2.8 default for every window — over-counting heat loss
on the ~852 windows the survey dates to 2002-2021 (RdSAP Table 24 U=2.0).

Add `_pashub_glazing_type_int` mapping the surveyed labels to the SAP10
cascade glazing codes the calculator reads for window U
(`_GLAZING_CODE_TO_UWINDOW`) and solar g (`_G_PERPENDICULAR_BY_GLAZING_TYPE`):
before 2002 -> 3, 2002-2021 -> 2, unknown install date -> 3 (pre-2002
default), post-2022 -> 13. Strict-raises `UnmappedPasHubLabel` on an unknown
label; blank passes through as "".

Completes the fabric stack (party-wall/wall-construction/insulation/glazing):
cohort MAE 2.79 -> 2.66, within-0.5 11.4% -> 12.9%, signed -0.04 -> +0.33.

Closes #1562
