15 new features wired through schema -> domain -> mapper -> transform:
Main Dwelling fabric (11):
- wall_insulation_type, wall_insulation_thickness_mm, wall_dry_lined,
wall_thickness_mm, party_wall_construction
- roof_insulation_location, roof_insulation_thickness_mm
- floor_construction, floor_insulation, floor_insulation_thickness_mm,
floor_heat_loss
Dwelling-level scalars (4):
- multiple_glazed_proportion, number_baths, number_baths_wwhrs,
extract_fans_count
Thickness strings like '50mm'/'NI'/'ND' parsed via _parse_thickness_mm; NI
(no insulation) lands as 0mm so the model sees the physical zero rather than
a missing value. Categorical sentinels ('NA'/'NI'/'ND') become None.
Also fixed long-standing typo `multiple_glazed_propertion` -> `_proportion`
in domain dataclass + its lone DB-model usage.

Two production fixes surfaced by the live run:
- mapper.from_rdsap_schema_21_0_1 now sets the three ML target scalars
(energy_rating_current, co2_emissions_current, energy_consumption_current).
They were silently None for every cert before, leaving the only labels as
the kWh fields from renewable_heat_incentive.
- train_baseline coerces object-dtype columns to numeric (None -> NaN) and
drops rows with null target per fit, so LightGBM accepts the frame.
E2E on 500 real certs (~1s):
sap_score R^2=0.604 MAPE=0.084
co2_emissions R^2=0.813 MAPE=0.130
peui_raw R^2=0.979 MAPE=0.026
space_heating_kwh R^2=0.823 MAPE=0.213
hot_water_kwh R^2=0.519 MAPE=0.115
peui_ucl excluded: UCL correction still needs wiring.

Currently fails on SapWindow.glazing_gap (first of ~30 fields the dataclass
incorrectly treats as required). Will go GREEN once 14j sweeps Optional.

SAP10 EPCs with measured PV carry photovoltaic_supply as a nested
list of arrays (peak_power, pitch, orientation, overshading) rather
than the legacy unmeasured wrapper {none_or_no_details:
{percent_roof_area: N}}. The schema-21 dataclasses now accept both
shapes via Union[PhotovoltaicSupply, List[List[PhotovoltaicArray]]],
and from_dict._coerce now dispatches list values onto list type
variants of multi-type Unions.
EpcPropertyData.SapEnergySource gains
photovoltaic_arrays: Optional[List[PhotovoltaicArray]] — populated
when the measured shape is present, otherwise None. The legacy
photovoltaic_supply field is preserved for the fallback case.
Both schema-21.0.0 and 21.0.1 mappers dispatch via the new
_map_schema_21_pv helper.
Unblocks Slice 11 (PV feature aggregation in EpcMlTransform).

Thirteen window-aggregate features land on the transform: count,
total area, eight SAP-octant area columns (N/NE/E/SE/S/SW/W/NW),
area-weighted draught-proofing pct, and area-weighted u_value +
solar transmittance (nullable, populated only when windows carry
transmission_details). Windows with orientation outside 1-8 (0,
NR) contribute to count and total area but no octant.
Also: epc codes CSV (gov api /api/codes export, RdSAP-Schema-21.x +
older versions) moved next to EpcPropertyData as epc_codes.csv —
canonical SAP enum source for upcoming categorical-share slices.
.gitignore exception added so the reference CSV is tracked.
