chore: stage cert 0330 fixtures (boiler pilot)

Browse source 
Adds the (API JSON + Summary PDF) fixtures for cert
0330-2249-8150-2326-4121 — the boiler pilot identified in the
handover. Property: 17 Summerfield Road, MANCHESTER M22 1AE
(mid-terrace house, mains gas boiler PCDB idx 10241, age D).

Source: API JSON fetched via EpcClientService from
https://api.get-energy-performance-data.communities.gov.uk
(OPEN_EPC_API_TOKEN). Summary PDF copied from
`sap worksheets/Additional data with api/0330-2249-8150-2326-4121/
Summary_000897.pdf` (where the user provided the triple).

Worksheet target: SAP 61.5993 (continuous), from `dr87-0001-000897
.pdf` in the same source directory.

Current state on these fixtures (uncommitted before this slice):
  - Summary mapper cascade SAP: 62.0660 (Δ +0.4667 vs worksheet)
  - API mapper cascade SAP:     63.7446 (Δ +2.1453 vs worksheet)

Both paths RED at 1e-4. Two specific cascade-component gaps
identified in the handover for follow-up slices:

  1. Windows HLC +6.71 W/K (API vs Summary) — likely glazing_type=14
     not in Slice 93's `_API_GLAZING_TYPE_TO_TRANSMISSION` (only
     codes 3 and 13 mapped).
  2. HW kWh +1060 (API 3172.65 vs Summary 2112.00) — §4 subsystem
     gap; needs occupancy/shower/cylinder probe.

This commit stages the fixtures only — no tests added yet. The
follow-up slice should add a RED Layer 2 test (Summary path 1e-4
vs 61.5993) and proceed slice-by-slice.
