fix(offload): return on-demand components to rest after bulk moves

A pipeline-level move to the accelerator carries on-demand components
along with it, since modular pipelines skip only group-hooked modules;
the load path then left a resting vae on the gpu until its first use.
Bulk moves now re-evict stamped components, whose entry points onload
them when needed.
