Read showImported from register.json as fallback

If showImported is not explicitly set via window.bblocksViewer or URL/env
params, apply the value from the local register's viewer.showImported field
(written by bblocks-postprocess). config.service exports a setShowImported
method that owns the precedence logic and normalisation.
