feat(simulation): auto-pause sim on implant-fullscreen — inspection substrate (T-970)

D-226 layer 1. World-advancing phases gated on pause: Movement/Storyteller/Knowledge/TickAdvance set-gated via sim_not_paused; Simulation + Economy gated per-system at their registration sites — collect_sound_events and serve_econ_state_query stay unconditioned (transient-buffer clear + paused-allowed query; set-gating Simulation leaked a stale tick-7 footstep into frozen snapshots — caught by golden_suite, fixed without touching the fixture; regression test encodes the bug shape). New PlayerAction::AutoPause/AutoResume + AutoPauseState resource implement Option A reconciliation: auto-resume only fires if auto-pause caused the pause; manual pause and Half rate survive implant open/close. PauseParams SystemParam bundle keeps process_player_input under the 16-param ceiling (BookmarkInputParams precedent). Client: HudGroups.gameplay_occluded now sends AutoPause/AutoResume via send_named_action; 5 gdUnit tests + 7 Rust tests.
