Khalim Conn-Kowlessar f3e3494bf7 test(worksheet): pin simulated case 52 — regular gas boiler + cylinder ...

Adds the mapper-driven e2e cascade pin for "simulated case 52" (000565
semi + regular non-combi mains-gas boiler SAP 102 + 160 L foam cylinder
heated from the main, no cylinder stat, uninsulated primary pipework,
standard tariff). Routes the Summary PDF through extractor + mapper +
calculator like the other 000565 / 001431_case* fixtures.

This closes the last untested branch of the cylinder/water chain: the
SAP 10.2 §4 cylinder storage loss (Table 2/2a/2b lines 51-55) + the
Table 3 PRIMARY circuit loss (59, uninsulated pipework + no stat) that
combi/immersion fixtures don't reach. All 11 SAP-result fields reconcile
to the U985 worksheet EXACTLY with no calculator change — SAP 57.2904
(=57), cost £911.1973, water 3929.7635 kWh — confirming the cylinder-loss
derivation is correct.

Summary mirrored to the tracked fixtures dir so the test doesn't depend
on the unstaged `sap worksheets/` workspace.
