Fix camera flip bugs, refactor camera (#11)
* Fix 180-degree camera flip when exiting sub-worlds without cam anim

When returning from sub-worlds (jukebox, hospital exterior, etc.) with
3rd person camera active, the camera/player flipped 180 degrees. This
happened because SpawnPlayer calls Enter() → TurnAround() before
PlaceActor(), and PlaceActor overwrites the ROI direction with the
path's standard convention (z = forward). For spawn points with cam
anims, OnCamAnimEnd corrected this, but spawn points with m_location=0
(like jukebox exterior) had no correction.

Replace m_roiUnflipped with m_needsDirectionFlip flag that tracks world
transitions. OnWorldEnabled sets the flag, and the first Tick after
PlaceActor completes flips the ROI to backward-z and re-setups the
camera. ReinitForCharacter now always flips the ROI direction, handling
both Disable→Enable toggles and enabling 3rd person after a 1st-person
spawn.

* Fix camera flip regressions for vehicle exit and world transitions

The unconditional ROI flip in ReinitForCharacter caused a 180-degree
flip when exiting vehicles (Enter's TurnAround follows and double-flips).
Restore conditional flip using m_roiUnflipped, but now also set it in
OnWorldEnabled (even when disabled) so cold-enabling 3rd person after a
world transition correctly flips from PlaceActor's forward-z.

Key changes:
- Remove m_roiUnflipped clearing from OnActorEnter: Enter() is always
  followed by PlaceActor which overwrites the ROI, so clearing the flag
  prematurely caused the cold-enable case to miss the needed flip.
- Add orbit camera override in OnActorEnter during world transitions
  (m_needsDirectionFlip && m_active) to suppress the 1st-person camera
  flash from Enter's TransformPointOfView.
- Clear m_roiUnflipped in OnCamAnimEnd alongside m_needsDirectionFlip,
  since the cam anim's PlaceActor + flip handles the correction.

* Defer orbit camera setup during world transition loading freeze

Remove the premature SetupCamera call from OnActorEnter's world
transition path. The stale orbit camera view (computed before
PlaceActor runs) would freeze on screen during the ~500ms world
load, appearing as a wrong-direction flash. The Tick correction
after PlaceActor now handles the initial orbit camera setup at
the correct position.

* Skip orbit camera while cam anim is running to prevent actor glitch

When a cam anim plays with 3rd-person camera active, ApplyOrbitCamera
was fighting the cam anim each frame. If the cam anim was interrupted
(space bar), its end handler read the ViewROI position — which was set
by our orbit camera (elevated, behind player) — and placed the actor
at that position, causing it to glitch into the air.

* Add documentation for ROI direction conventions and camera corrections

Documents the forward-z vs backward-z conventions, all code paths that
require direction correction, and the flags that coordinate them.

* Refactor 3rd-person camera from backward-z to forward-z convention

Switch the orbit camera to use forward-z (matching PlaceActor's native
output), eliminating all FlipROIDirection/TurnAround corrections. The
display clone flips to backward-z when syncing from the native ROI so
character meshes face correctly. Use actor state (c_disabled) instead of
m_animRunning to guard against cam anim conflicts, allowing the orbit
camera to resume as soon as the player is released.
