Add reactions (Sheklak), fix hakem card visibility during trump choice

- Reactions/emotes in-game: tray of owned emojis + animated per-seat bubbles
  (feature named "شکلک / Sheklak"). Packs: starter (free), champion/legend
  (earned by rating/wins), emotions/taunt (purchasable in shop)
- OnlineService.sendReaction/onReaction; mock echoes you + random opponents
- Fix: human hakem's 5 cards were blurred behind the trump-chooser overlay —
  raise hand to z-50 during choosing-trump so cards stay readable
