Subject: [PATCH] Support SelectableParagraph in fantom tester

Summary:
The fantom test renderer only rendered text children for Paragraph nodes and
its stub component registry did not register the SelectableParagraph
descriptor, so selectable text fell back to an unimplemented view with empty
output. Register the SelectableParagraph descriptor and render its children
from ParagraphState the same way as Paragraph, so selectable text stays
observable in test output.

Changelog: [Internal]
