remove obsolete sig-select FTs (S1/S3/S4) based on old sequential 36-card design

The new sig-select has two parallel 18-card overlays per polarity group (levity:
PC/NC/SC; gravity: BC/EC/AC) — no shared 36-card deck, no active-seat turn order.
S1 (36 cards), S3 (PC picks → deck shrinks → active advances to NC), and S4
(non-active seat blocked) all tested the old design and have been failing in CI.
S2 (seat display order) passed and is kept. Header comment updated to match.
