feat(world): port retail portal-space viewport

Browse source 
Replace the opaque teleport cover with the DAT-authored CreatureMode tunnel, exact retail camera/light/animation timing and easing, and animation-hook audio routing. Compose portal and fade passes below retained UI so gameplay windows and input remain active through F751 travel.

This is the asynchronous adapter for retail's direct full-`Position` placement
(`SmartBox::TeleportPlayer @ 0x00453910`).
### Portal-space presentation boundary
`TeleportAnimSequencer` is the pure Core owner of retail's seven-state
teleport lifecycle, exact 1/2/5-second thresholds, frame-aligned exit window,
and 100-sample `UIGlobals::GetAnimLevel` fade curve. App-layer
`PortalTunnelPresentation` owns the synthetic DAT Setup (`0x02000306`), its
40-frame/s animation (`0x030005AC`), `CSequence`, SmartBox-FOV camera, distant light, mesh
references, and animation-hook delivery. It renders through the existing
modern `WbDrawDispatcher` as a replacement 3-D viewport, after world rendering
and before retained UI. The shared dispatcher is reset to no world-cell clips
and no world point lights for this pass. Chat, gameplay windows, toolbar,
cursor, and input continue normally above it. The synthetic object never
enters `LiveEntityRuntime`, collision, picking, radar, or server GUID state.
The destination residency gate supplies retail's `EndTeleportAnimation` edge
once asynchronous streaming is ready. Player placement remains authoritative
and separate from presentation; arrival does not reset the character animation
sequence. See `docs/research/2026-07-15-retail-portal-space-pseudocode.md`.
## Roadmap Model
The old R1-R8 architecture sequence was a useful early refactor sketch, but it
