fix(editor): terrain raycast on rough terrain, keyboard shortcuts, context menu

Browse source 
- Raycast AABB now uses actual min/max vertex heights per chunk
  instead of fixed ±200 padding (fixes misses on sculpted terrain)
- Right-click context menu opens correctly (deferred popup via flag
  since ImGui::OpenPopup must be called within ImGui frame)
- Keyboard shortcuts: G=Move, R=Rotate, T=Scale, X/Y=axis lock,
  Escape=deselect, Delete works in any mode for objects/NPCs
- Delete key now removes selected NPC in NPC mode too
