Remove stucklaunch; add valuable-item ESP

- Drop the stucklaunch feature, its settings, diagnostics and
  m_hGroundEntity resolution.
- Add a Visuals feature that scans the client entity list for valuable
  pickups: health/medkits/chargers, ammo boxes/crates/grenades, batteries,
  HEV suit modules/chargers, supply crates and generic items.
- Model-first classification with class fallbacks; category toggles, distance
  labels and a max-distance slider.
- Draw colored marker/label tags through walls, independent of the hostile NPC
  ESP.
- Persist [items] active/bind/health/ammo/armor/crates/distance/max_dist;
  Reset restores defaults; GUI card and CONTEXT updated.
