Implement the translocation sphere -- the "blue warp" respawn effect (task #52)

Browse Source 
BTTranslocationRenderable was a no-op stub; now reconstructed over the engine's
POVTranslocateRenderable: loads tsphere.bgf and runs a collapse-on-arrival /
expand-on-reveal sphere (scale 100->1 over 1.3s, then 1->150 over 1.0s, rotating)
keyed on the player's SimulationState dial. Drawn direct from the render loop by
BTDrawTranslocationSpheres (beside BTDrawBeams, PASS_ALPHABLEND) -- the same
accommodation the beams/reticle use.

The asset loads by FILENAME (tsphere.bgf), not through the RES table -- which is
why every resource-name search missed the effect for three rounds.

Trigger wiring: btl4vid.cpp MakeEntityRenderables builds the sphere for the LOCAL
player (the authentic wiring builds it only for replicants + a POV fade for self,
but peer player-attribute replication isn't wired -- on a replicant SimulationState/
DropZoneLocation read uninitialised). btplayer.cpp pulses SimulationState
DropZoneAcquired->VehicleTranslocated at respawn (a 1.4s flip timer stands in for
the engine's +1s drop-zone re-post) and writes the respawn origin into the
DropZoneLocation attribute.

Verified 2-node (BT_TLOC_LOG): on respawn the sphere collapses (~100->5) then
expands (->150) at the valid drop-zone origin, deduped to <=2 active, respawn
cycle un-regressed, no render errors. Visual appearance (colour/size) still needs
a live look; the authentic see-others'-spheres path needs player replication.
