Khalim Conn-Kowlessar 9cb79d9c98 Slice 26: §5 internal gains cascade pin (50/54 PASS) + rooflight daylight plumb 
Added `internal_gains_section_from_cert` helper composing §1 (volume) +
§4 (heat_gains line 65)m → §5 orchestrator, and 54 strict pin cases for
worksheet lines (66)..(73) monthly + (232) annual lighting kWh.

Also fixed a missing input plumb: cert_to_inputs was passing
`rooflight_total_area_m2=0` to `internal_gains_from_cert`, so the
000516 roof window (lodged on `epc.sap_roof_windows` since slice 24)
wasn't contributing to the L2a daylight factor. Added
`_rooflight_total_area_m2_from_cert` and routed it through both the
public cert→inputs cascade and the new §5 section helper.

§5 cascade:

Remaining failures are 000477 + 000487 LINE_72/73 — cascaded from §4
LINE_65 heat_gains residuals (000477 combi loss, 000487 HW lodgement
defect). Both fixtures are slice 25 territory.

Scoreboard:
  section_cascade_pins: 170 → 220 PASS (+50; 54 new tests, 4 fail)
  e2e SapResult:        29 →  30 PASS (+1, downstream from rooflight plumb)
