Improve the auto creation feature

 NXP-27574 introduce different changes on both sides UI and Server.

When dealing with the  NXP-27574 we observers that some exiting codes can be improved like:

 Refactor the code responsible of creation the Nuxeo documents of the Transfer files 

• Replace the process creating those documents by using a computation instead of A Worker 
• Add more integration tests: S3...

 This new ticket will be responsible to deal with the points above but also dealing with the remarques (FIXME, TODO) that we left when dealing NXP-27574 like for example  here to be more consistent we should look for the FIXME and TODO and correct them.

as UI improvements:

• improve the JS documentation
• avoid duplication between for example transfer summary and meta data by using the introduced behaviour for exemple to avoid make same code  to retrieve infos from server.
• I don't know if we have a dedicated ticket but we should try to find a best solution for the refresh on a list of transfer because it makes some inconsistency
• We should also deal the automatique creation of a transfer, some times it seems for me that it's not visible on UI and when we try to create a new one it ended with an error and there an existing code which disable the polling at then end the new created transfer will in the wrong state ....
