Shokunin 465f926ecf netplay: confirm against every peer, shed the own view when behind, progress-based stall timeout

Four-peer rollback desynced under load (R4, host behind): the guests
predicted the slow host's pad, hash-confirmed the tick among themselves
through the one shared peer ring, then promoted the host's real pad into
history only (hc-silent promote) while the host simulated it. The host
stayed forked; its recovery episode was then refused as a "zombie load"
behind the guests' (wrongly) agreed tip.

- Hash confirm is a quorum over every occupied peer seat
  (rnet_hc_set_peer_mask / note_peer_from, recomp-net) for three or more
  seats; two seats keep the one-peer chain.
- A peer more than 4 ticks behind the others' inputs sheds its own view
  (psx_mod_render_local_view status FAST_FORWARD, held 60 ticks), so the
  presentation-only pass goes before the simulation slips.
  PSX_NET_LOCAL_VIEW_SHED=0 keeps it.
- The admit-stall watchdog counts time without progress: a remote input tip
  that advances restarts it, so a slow peer is waited for.
  PSX_NET_ADMIT_STALL_MS (20000) and PSX_NET_LIVENESS_MS (1500) configure it.
- Pins recomp-net fix/rollback-span-stall.
