Stucklaunch: fix prop detection and add diagnostics

- Client physics props are CPhysicsProp/CPhysBox, not the server class
  prop_physics; the old case-sensitive class check never matched. Detect
  MOVETYPE_VPHYSICS first (the reliable signal), then case-insensitive
  class/model patterns.
- Log the first few prop checks with index, movetype, class and model so a
  failed ground lookup is diagnosable.
- Log once when Stucklaunch is active (with run state, bind and ground
  offset), when it engages, and when the ground is not a prop.
- Toast a warning when binding a feature that is not Active yet.
