Use search instead of findMany in relation pickers (#7798)

First step of #https://github.com/twentyhq/twenty/issues/3298.
Here we update the search endpoint to allow for a filter argument, which
we currently use in the relation pickers to restrict or exclude ids from
search.
In a future PR we will try to simplify the search logic in the FE
