test(ui): run the Home recent Reveal test inline so its toast check can't race

home_recent_context_menu_reveals_the_target_without_opening_or_removing_it
never set run_inline, so reveal_path checked the missing file on a
pdfcraft-reveal worker thread while the test waited a fixed three frames
before asserting the "The file no longer exists" toast. On a loaded runner
the worker can report after those frames and the assertion fails. Set
run_inline, as the reveal unit test in tab_context.rs already does.
