Fix overlay-vanishing projections; ammo rule via held weapons

- world_to_screen now rejects NaN/inf and absurd projections. A point on the
  view axis (directly below the feet) could produce NaN and corrupt the
  ISurface clip state, hiding the whole ESP for that frame.
- Draw projectile radius rings even when the projectile centre is off-screen
  or behind the camera.
- Owner netvars are -1 on this client, so the "owned weapon -> ammo" rule now
  accumulates the weapon types the player has actually held (active weapon,
  server fallback), reset when the local entity changes.
