fix #270: retry spawn placement until first success (lost-cell recovery analog) + attributed probes

Browse source 
The creation-only spawn placement could no-op or fail during the login
flood (cell id not yet hydrated / streaming collision not resident) with
nothing retrying - monsters created in that window stayed
airborne-flagged forever and their action animations remained refused.
Retail's answer to 'object addressed before its cell exists' is the
CObjectMaint lost-cell list (GotoLostCell): park, re-place when the cell
is available. The UM dispatch path now retries SeedRemoteSpawnPlacement
while the body has never been successfully placed (no contact AND no
stored plane); one success ends the retries.

Probes: [SPAWN-PLACE] logs each placement outcome (guid/cell/ok/
contact/walkable); [UM-ACT]/[MT-FAIL] now carry the owning guid via
MotionInterpreter.DiagnosticGuid (probe-identity-attribution lesson)
plus the body's live contact/walkable flags.
