Khalim Conn-Kowlessar ed15bd13f7 Map PasHub walls_insulation_type labels to SAP10 codes
`from_site_notes` copied the raw `walls_insulation_type` survey label onto
the building part; the calculator's `_int_or_none` read it as `None`, so
the ~101 filled-cavity walls in the cohort lost their lower-U credit and
were over-counted.

Add `_pashub_wall_insulation_type_int` (mirroring the wall-construction
helper and the Elmhurst `_ELMHURST_WALL_INSULATION_TO_SAP10` sibling)
mapping the surveyed labels to the SAP10 wall-insulation codes `u_wall`
consumes ("As built" -> 4 assumed/default, "Filled Cavity" -> 2,
"External" -> 1), strict-raising `UnmappedPasHubLabel` on an unknown label.

Stacked on #1560, this is the fabric fix that removes the cohort's
systematic SAP bias: mean signed -0.79 -> -0.04, MAE 3.11 -> 2.79,
within-0.5 8.5% -> 11.4%.

Closes #1561
