- Add response.json() calls in nfo-manager.js for all API calls
- Add response.json() calls in nfo-config.js for all API calls
- Fix createNFO, refreshNFO, viewNFO, getSeriesWithoutNFO functions
- Fix load and testTMDBConnection functions
- All API responses must be parsed before accessing properties
