Add particle visualization for wand selection

- Add WandParticleService to show particles around selected wand areas
- Show green particles at corner 1 (pos1)
- Show cyan particles at corner 2 (pos2)
- Show yellow/green edge particles around the selected cuboid
- Show gray outline for other ready slots (lower intensity)
- Particles visible only to the player holding the wand
- Start particles when selection is made or wand is held
- Stop particles when player switches away or disconnects
