Asset Catalog Service: add function to change catalog path

Add `AssetCatalogService::update_catalog_path()` to change the catalog
path of the given catalog, and also change the path of all the catalogs
contained within the given catalog.

Rebuilds the tree structure for the UI, but does not save the new catalog
definitions to disk.

No user-facing changes, just backend preparation for UI work.
