fix(editor): NPC nameplates align with NPC + togglable to selected only

Browse source 
Three issues fixed in one pass:

1. Z-offset was 35 yards — nameplates floated way above the actual
   NPC position. Dropped to 3.5 yards (just above an average
   creature's head) so the label reads as attached.

2. Horizontal alignment was a fixed -30 px offset, which only looked
   centered for ~6-character names. Switched to ImGui::CalcTextSize
   and centering on the projected position.

3. Nameplates were always-on, which got noisy fast on populated
   zones. Added "Nameplate on selected only" checkbox in the NPC
   panel (default ON); when unchecked, all NPCs show their names.

Vertical position also slightly tightened (sy - textSz.y - 2 vs
sy - 10) so the text baseline aligns rather than floating below.
