Added the Scene Manager (Libreflow casting, load, update, assetize)

New Scene Manager panel (WTD tab) talking to a running Libreflow through
its IPC server and the wtdcmds commands: pick the shot context, read the
casting, link the latest available publishes (overrides for chars and
props, collection instances otherwise), flag out-of-date versions in red,
update / roll back / remove loaded assets, and publish local collections
as assets. Requests run in the background. Settings in config.py
(SCENE_MANAGER_*, LIBREFLOW_*).

The Shot Viewer groups rigs loaded by the Scene Manager by asset type.
The manifest declares the network permission.
