fix(og): resolve font corruption and Next.js 15+ params compatibility

- Replaced corrupted HTML font files with binary WOFF2 versions.
- Updated all opengraph-image.tsx files to await params, as required by Next.js 15+.
- Improved OG image reliability by using SITE_URL for absolute image paths.
- Added scripts/check-og-images.ts for automated production verification.
- Integrated smoke_test job into deployment pipeline.
