Tests: Verify View intent blocks suggestion overlay and commit bar

Add a unit test confirming the HOC passes through in View intent (no
overlay diversion — real setAttributes is invoked) and an e2e test
verifying that switching from Suggest to View hides the commit bar
and prevents suggestion leakage into post content. Both validate that
isPreviewMode + intent gating work together correctly.
