fix(og): verified font and infrastructure fix
- Fixed font corruption: Replaced WOFF2/HTML stubs with valid binary WOFF fonts.
- Verified local rendering: check:og script now passes on local production build.
- Robust infrastructure: Guaranteed Traefik bypass with Host match and priority 2000.
- Middleware bypass: Ensured OG routes are never intercepted by next-intl.
