ui: raise in-game emoji button above the hand + gender = male/female/unknown

- GameTable reactions button (and its tray) moved up from the bottom-right so it
  no longer overlaps the player's cards on mobile portrait.
- Gender options are now Male / Female / Unknown — removed "other" from the
  Gender type, GENDER_META, and the profile picker; the empty value renders as
  «نامشخص» / "Unknown".
