fix(render): FW4 - static-owner particles submit at their walk turns

Ports the user-verified #132 invariant (e102fb36 on the old pipeline)
walk-natively, on the owner''s direction: retail''s falls containment
is POSITIONAL - an outdoor emitter''s polys join the ONE alpha list
during its owner cell''s DrawObjCell in the far-to-near landscape walk
(DrawSortCell @0x005a17c0), so every nearer building''s pre-punch
barrier (DrawBuilding @0x0059f2a0''s FlushAlphaList @0x0059f30b)
drains the already-queued FARTHER content against still-true depth
BEFORE its punch stamps far-Z into the aperture. The walk path had
kept the per-building AlphaBarrier events but batched ALL landscape
static-owner submission into one lump at the pre-clear closure - after
every punch had run: the barriers fired over an empty queue and the
falls drained against punched-far aperture pixels (phase=pre in every
probe line, which is why six rounds of phase-staging repairs could
never see it - the phase was right, the position within the phase was
wrong).

New WalkFrameEventKind.StaticParticles: each landscape cell''s and
each building shell''s emitter owners now submit AT THAT TURN during
Replay (marked so the owner''s meshes flush first - retail''s
per-object order); the batched SubmitWalkLandscapeStaticParticles and
its closure/post-replay call sites are deleted for both root kinds.
Two driver sequence pins adjudicated to the new turn order.

Hermetic 6,762/0; InstalledDat walk conformance 40/1.
