FormPopulationConfig

Helper to bridge configuration storage for form population between legacy namespaced attributes and the PSR-7 attribute bag on WebRequest.

WebRequest is immutable, so seed()/merge()/setScopedValue()/store() return the (possibly new) request instance; callers must capture and propagate it. Legacy namespaced-attribute holders mutate in place and are returned unchanged for API symmetry.
