VideoGenerator.from_pretrained accepts the 24 common engine and offload
keywords in FROM_PRETRAINED_KWARGS. Any other keyword raises TypeError
with the config path to use with VideoGenerator.from_config. The
conversion of the removed flat keywords (LTX-2 refine names, component
config prefixes, pipeline_config objects, empty-string paths) is removed
from from_pretrained_kwargs_to_config.
The golden kwargs cases that used removed keywords move to a config
category of typed configs; their golden files are byte-identical. The
DreamVerse contract test and the GPU pool forward-translation tests
checked only the removed keyword mapping; the GPU pool tests keep the
typed-config flattening checks.
