Khalim Conn-Kowlessar 17646c8ae9 chore: stage cert 0380 fixtures (HP pilot — deferred workstream) ...

Adds the (API JSON + Summary PDF) fixtures for cert
0380-2471-3250-2596-8761 — the Air Source Heat Pump pilot
identified in the handover. Property: 16 Beech Lea, WIGTON CA7 5JY
(semi-detached bungalow, ASHP PCDB idx 104568).

Source: API JSON fetched via EpcClientService. Summary PDF copied
from `sap worksheets/Additional data with api/
0380-2471-3250-2596-8761/Summary_000899.pdf`.

Worksheet target: SAP 88.5104 (continuous), from `dr87-0001-000899
.pdf`.

**This is the HP pilot, intentionally deferred.** Initial probe on
these fixtures (uncommitted before this slice):
  - Summary mapper cascade SAP: 18.08 (Δ -70.43 vs worksheet)
  - API mapper cascade SAP:     70.14 (Δ -18.37 vs worksheet)

Both paths are catastrophically RED. The mapper has never been
validated against an ASHP cert and there's substantial cascade
plumbing required:

  - API mapper correctly identifies the HP (COP 2.3) but fabric HLC
    is 104 W/K vs the ~50 W/K needed for SAP 88.51.
  - Summary mapper misreads the HP as an 80%-efficient boiler
    (catastrophic).
  - 7 of 9 newly-staged certs are ASHPs (6 share PCDB idx 104568,
    cert 9418 uses 102421), so a shared HP-cascade fix will likely
    close most of them at once.

Stashed here so the next agent can pick up the HP workstream
without needing to refetch from the EPB API. Recommend not
attempting these slices until the boiler workflow (cert 0330) is
proven; the boiler cascade is the reference shape and HP work
should build on a known-good baseline. Handover §"Heat-pump
workstream sketch" outlines the likely 15-30 slice queue.
