feat(console): add SWR caching to changelog endpoints

- Add Cloudflare edge caching (cf.cacheTtl) for GitHub API requests
- Add Cache-Control headers with s-maxage=300 and stale-while-revalidate=600
- Refactor /changelog to fetch from /changelog.json instead of GitHub directly
- Remove duplicate parsing logic from changelog page
