Subject: [PATCH] fix: guard page.url for falsy values in ogSlug computation

Pages with permalink:false (like about.njk) have page.url as false,
which crashes inline string operations. Use the ogSlug filter with
(page.url or "") guard to handle falsy values safely. Also removes
debug comment from previous debugging session.
