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
- make member nullable on favorites
- add potential relation with view entity
- add a new type of favorite list in front : workspace favorite
- build a new component for retrieving workspace favorite to display +
refacto the existing one
Bonus:
- removing activities seed since this is deprecated
