test(rtx-fsi): RTX_FSI{2,3}_ES stiffness override for the TWIN-2 parameter sweep

The second knob of the TWIN-2 campaign (omni-cortex docs/twin2_stiffness_campaign.md): case_from_env now also reads RTX_{prefix}_ES over the case's benchmark Young's modulus, mirroring UMEAN exactly — digit-identical with the knob unset (verified in vivo on BOTH committed defaults against same-day baselines: FSI2 and FSI3 physics lines diff-clean, only compile/wall timings moved), a loud override line naming the benchmark value and E/E0 when set. The benchmark-inflow physics-band guard in both turek_hron tests widens to a benchmark-CASE guard (u_mean AND e_s bit-identical) so no measured band ever asserts off-benchmark; machinery invariants stay asserted at every inflow and stiffness.
