I would address this using component parameters to tell the components
where they can obtain those resources from. Perhaps there's a
ResourcesProvider interface that a page could implement.
The default for the parameter could be "componentResources.page",
which would provide the containing page, cast to ResourcesProvider.
For AppPropertyBlocks, you'll need to bind the parameter more
directly, to whatever works as a proper ResourcesProvider.
Does that help?
Could you move the resource provider to a service, instead of the page?
