feat: migrate community workflows to R2 storage

- Update API routes to fetch from nodebananapro.com
- Remove local workflow JSON files (now hosted on R2)
- Remove LFS tracking (.gitattributes)
- Remove local communityWorkflows.ts metadata (now on server)
- Add COMMUNITY_WORKFLOWS_API_URL env variable option
