Aggregated queries #1 (#8345)

First step of https://github.com/twentyhq/twenty/issues/6868 Adds min.., max.. queries for DATETIME fields adds min.., max.., avg.., sum.. queries for NUMBER fields (count distinct operation and composite fields such as CURRENCY handling will be dealt with in a future PR) <img width="1422" alt="Capture d’écran 2024-11-06 à 15 48 46" src="https://github.com/user-attachments/assets/4bcdece0-ad3e-4536-9720-fe4044a36719"> --------- Co-authored-by: Charles Bochet <charles@twenty.com> Co-authored-by: Weiko <corentin@twenty.com>
