feat(hs): disable wings in-event + periodic HUD-state packet/broadcast

- HeykelSavasiContext.IsItemAllowedToEquip disallows wings/capes during
  Playing only (so entry is never rejected for wearing wings); auto-unequips
  any equipped wing/cape into a free inventory slot in OnGameStartAsync.
- New S2C packet HeykelSavasiHudState (C1, code FB, length 11) carrying
  phase, team, counts, statue progress and remaining seconds, plus its view
  plugin/interface, broadcast once per second across registration/prep/
  battle and one-shot on join/statue-break/game-end.
