This PR fixes issues with one to many activity target bugs described
here :
https://github.com/twentyhq/twenty/issues/14280#issuecomment-3490170714

It also improves the request that fetches notes and tasks in index
pages, to only fetch the notes and tasks identifier fields, thus
reducing the amount of network load.
