fix(workflow-search): unclip block-name highlight shadow on the left (#4670)

The editor title h2 uses truncate (overflow:hidden) so the search highlight's -3px box-shadow was getting clipped on the left, exposing the mark's sharp edge. Replaces overflow:hidden with overflow:clip plus a 3px overflow-clip-margin so the shadow can bleed past the clip boundary without shifting the title text or breaking truncation.
