Slice 85: bulk-update cohort 000516 hand-built for Cat A diff parity

Closes 23 of 24 mapper-vs-hand-built load-bearing divergences by
populating fields the Elmhurst mapper extracts from Summary_000516.
pdf but the original hand-built left at their `make_minimal_sap10_
epc` / dataclass-default values. Every change is cascade-equivalent —
all 11 `_FIXTURE_PINS["000516"]` SapResult pins remain GREEN against
worksheet `SAP value 62.7937`.

000516-specific deltas:

- `wall_thickness_measured=True` on Main (Summary lodges 400 mm).
- `floor_type="Above unheated space"` (exposed timber floor, not
  Ground floor) — matches the cert's `is_exposed_floor=True` for
  the lowest Main floor.
- `roof_insulation_location="None"` — the Summary lodges the literal
  string "None" for an uninsulated roof; mapper surfaces it
  verbatim.

Standard Cat A additions (per Slice 72/75/78/82 pattern): floor
descriptive fields, 6 ventilation zero counts, draught_lobby=True,
pressure_test="Not available", top-level descriptive strings +
booleans, `number_of_storeys=3` (Main ground + first + RIR),
shower_outlets="Non-electric shower",
central_heating_pump_age_str="Unknown".

Diff count: 24 → **1**. Remaining diff is `sap_windows: LEN 5 vs 2`
— closes via Slice 86.

Pyright net-zero on the touched fixture.
