Spawn converted hunters in place and smooth their reveal

Fix the in-place Conversion respawn snapping to the origin (0,0,0),
which surfaced when a hider was tagged mid wall-climb. The owner holds
authority over the NetworkTransform, so the server's Instantiate
position is ignored on the owner. Deliver the tagged world position
through a replicated _spawnOverride the server writes in OnNetworkSpawn,
and have the owner re-assert it before PlayerCharacterController's first
Update snapshots the kill-plane rescue target. This replaces the fragile
SpawnedMidSeek phase check.

Also hide a freshly converted hunter on other clients for a short
settle window (conversionRevealDelay) so nobody sees it pop in or
interpolate from the spawn frame; the shot hider is already despawned,
then the hunter cleanly materializes in its place.
