Slice S0380.117: re-pin golden PE residuals for 0240 + 6035 (track §15)

Slice S0380.116 rounded `A_RR_shell = 12.5 × √(A_RR_floor / 1.5)` to
2 d.p. per RdSAP 10 §15 (p.66). Two certs in the golden corpus have
RR-driven cascade paths that fire this rounding:

  0240 (TFA 118, age J, RR on BP[0]):    PE +12.4941 → +12.4933
  6035 (TFA 128, age A, RR + gas combi): PE +46.0936 → +46.0952

CO2 deltas on both are sub-1e-4 (display-precision noise) so those
pins stay. All 51 cohort-2 certs are unchanged — their A_RR_shell
paths either bypass the Simplified branch (Detailed RR with
`slope`/`flat_ceiling` roof lodgements) or have no RR.

Per [[feedback-golden-residuals-near-zero]] re-pin to track new
cascade output rather than absorb the drift into the test tolerance.
The ±0.01 PE / ±0.001 CO2 absolute tolerances on the pin stay; what
changes is the expected residual value.

Test still passes at ±0.0000 drift on all 53 certs post-repin.
