feat(erp-seat): Pfish-6 replaces run 7 — run-6 NVFP4 quant on both boxes, max-num-seqs 8->32

Operator ruling: run 6 is declared Pfish-6 and is the standing seat; run 7 is
retired (its gate failure was the detector bug fixed in cc42d76, but the run was
independently poor).

- served under its TRUE name Pfish-6; LiteLLM alias trial -> Pfish-6
- ana-ml2 :8021 and pfi-gx10 :8098, both at 262,144 ctx, same artifact
- SPEED: moe_backend=flashinfer_cutedsl PROVEN unusable here (engine init fails,
  'kernel does not support current device'); Marlin is correct for a weight-only
  scheme, and vLLM's 'no native FP4' warning is about the scheme not the card
- the real lever was max-num-seqs 8 -> 32: n=8 1269 tok/s and n=16 2170 tok/s,
  3.2x the old ceiling, with single-stream latency unchanged
- head-to-head measured: ana-ml2 is 4.1x FASTER than the GX10, not slower
