chore(G.3): strip the #133 temp diagnostics

Remove the throwaway probes added to diagnose the dungeon FPS/grey issues now that
they're fixed: the ACDREAM_LOG_FPS headless line + [cellreg] registration line
(GameWindow), and the [pv-trace] 0x0007 gate-widen + raw-NDC bbox addition to the
flap probe (PortalVisibilityBuilder, reverted to the pre-#133 form). The permanent
Phase-U.4c [flap]/[pv-trace] probes (ACDREAM_PROBE_FLAP) are kept as-is.
