Add a `compact` variant to SiteFooter (single-line copyright + legal links) and use it in the dashboard layout, replacing the divergent hard-coded inline footer. The dashboard footer is now i18n-aware, contrast-corrected, and adds the KVKK link for parity with the site footer. Both layouts now render from one component.
