fix: move OG service files to api/services for Vercel compatibility

- Move ogStore, ogHtml, and articleMeta from src/services/ to api/services/
- Update imports in article-og.ts and article-og-refresh.ts
- Update import paths in articleMeta.ts (lib/profile and src/config/relays)
- Remove old files from src/services/
- Clean up ESLint config to only reference api/**/*.ts

This fixes the ERR_MODULE_NOT_FOUND error on Vercel by ensuring
serverless functions can access the service modules.
