fix(server): resolve two compile errors blocking CI

- GameOrchestrator: remove duplicate local 'cupName' declaration inside
  loadNextMap() lambda (variable already declared at top of block)
- ElytraPhysicsSystem: replace player.isGliding() (not available in
  Minestom) with player.isOnGround() as the landing detection proxy;
  when the server confirms ground contact, flight.setFlying(false) is set
  so LandingResetSystem can detect the flying→landed transition
