feat: wiki badge and /wiki links in global search results

Override Harmony's search partials so results tagged by the wiki plugin
(isWikiArticle + wikiPath) show a gold Wiki badge and link to /wiki/...
instead of /post/..., in the quick-search dropdown and both /search views.
Forum results render unchanged; posts_list_item is shared with account and
group pages, where the flags are never set and the conditional no-ops.
