Display and update fields from fromManyObjects relations in Show card (#5801)

In this PR, we implement the display and update of fields from
fromManyObjects (e.g update Employees for a Company).

Product requirement
- update should be triggered at each box check/uncheck, not at lose of
focus

Left to do in upcoming PRs
- add the column in the table views (e.g. column "Employees" on
"Companies" table view)
- add "Add new" possibility when there is no records (as is currently
exists for "one" side of relations:)

- update cache after an update affecting other records (e.g "Listings"
have one "Person"; if listing A belonged to Person A but then we
attribute listing A to Person B, Person A is no longer owner of Listing
A. For the moment that would not be reflected immediatly leading, to
potential false information if information is accessed from cache)
- try to get rid of the glitch - we also have it on the task page
example. (probably) due to the fact that we are using a recoil state to
read, update then re-read
