refactor: update all scripts to use CouchDB instead of MongoDB

- Updated backend/scripts/seedBadges.js to use only CouchDB
- Removed MongoDB dependencies and conditional logic
- Created new scripts/seedBadges.js for root directory usage
- Updated scripts/migrate-production.js to make MongoDB migration optional
- Fixed module path resolution for all scripts to work from any directory
- Cleaned up scripts/migrate-to-couchdb.js imports
- All scripts now work with CouchDB service without MongoDB dependencies
