AiPanel.handleNavigateWikilink was double-resolving: it resolved the
wikilink target to an entry path, then passed the path to onOpenNote
which is notes.handleNavigateWikilink (expects a title-based target).
The path didn't match any entry's title, so navigation silently failed.
Fix: pass the wikilink target string directly to onOpenNote, letting
the parent's handleNavigateWikilink do the resolution.
Also enhanced the Playwright smoke test to verify click → tab opens.
