fix: make post-navigation and webmentions sidebar widgets functional

Post navigation now uses previousInCollection/nextInCollection filters to find adjacent posts (avoids Nunjucks loop scoping bug). Webmentions sidebar widget now uses webmentionsForUrl and webmentionsByType filters instead of non-existent filter function. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
