Rework of the edition of 1-N and N-N links: managed as a delta from the GUI down to the the lowest APIs.

- Fixes the management of obsolete linked data.
- N.744 Fixes concurrent modifications (example: a user modifies a team, another user modifies a person related to that same team). Still NOT fixed with the customer portal.
- N.849 Fixes links edition in the case some data are not allowed to the current user (organization silos) -TO BE TESTED
- #1145 Fixes the creation of duplicate links in one step (Server to NW Device)
- #1147 Fixes the update of duplicate links
