Adds three non-nullable booleans (solar_water_heating,
has_hot_water_cylinder, has_fixed_air_conditioning) and three
optional integer indicators (percent_draughtproofed,
energy_rating_average, environmental_impact_current). All direct
EpcPropertyData field reads.

Ten flat int counts added to the transform — door_count,
habitable/heated/wet/insulated_door counts, extensions, open
chimneys, and the three fixed-lighting bulb counts (CFL/LED/
incandescent). All non-nullable; direct EpcPropertyData field reads.

First feature column lands on the transform: schema() advertises
total_floor_area_m2 as a non-nullable float; to_row() emits the value
from EpcPropertyData.total_floor_area_m2 alongside the six targets.

Previous slice commits used -a-style and missed these new files;
imports in transform.py and test_transform.py would dangle on a
fresh checkout. Re-running pytest after this commit covers all four
EpcMlTransform tests cleanly.
