Proposed changes

• Change the "representation" key used in an investigation and knowledge for an observable of type "File".
• In the graph, make it possible to search an observable "File" by hash.
• Add more detail about the observable in the "Investigation Entity detail" card (hashes and names).
• On tooltip, add additional information about the observable (hashes and names).

@Gwendoline-FAVRE-FELIX I've pushed with this commit missing translation for "Additional names".

Also, the tooltip was not translated at all.

Otherwise, all good to me !
