Migrate to fetch API and/or latest Axios version

[gdoumen]

Currently Incyclist is using a mix of libraries to perform HTTP requests

• request API to send forms
• axios to perform downloads of big files, which can be paused/resumed and report on progress
• axios to retrieve resources identified by an URL

request API is out of live and will not be maintained anymore.
Axios is still maintained, but the latest versions are not working, i.e. we still are on an old version, which has security issues

Therefore, the app should try to migrate to fetch API (natively supported by NodeJS >v18) or Axios
