This PR adds what is necessary for having SSE working for view relations : fields, filters, filter groups and sorts. This should allow to have AI working well while creating views with detailed filtering and sorting. ## Demo https://github.com/user-attachments/assets/026c7fb5-8e1a-4498-b7f4-d16993e5a7c4 ## Fixes Also fixed in this PR while working on the filter area : - Advanced filter does not update - Advanced filter sub field selection is broken (due to Jotai migration) - No view fields when creating a new view - Error on advanced filter deletion (cascade delete wasn't taken into account on the frontend) - Bug advanced filter creation --------- Co-authored-by: Félix Malfait <felix.malfait@gmail.com>
