fix: view group followup (#9162)

This PR fixes all followup that @Bonapara add on Discord.

- [x] When no group by is set, clicking on group by should open the
"field selection" menu
- [x] When closed, chevron should be "chevron-right" instead of
"chevron-up"
- [x] Sort : Add ability to switch from alphabetical to manual when
moving a option in sort alphabetical
- [x] Add subtext for group by and sort
- [x] Group by menu display bug
- [x] Changing the sort should not close the menu
- [x] Group by Activation -> shows empty state + is slow
- [x] Switching from Kanban view Settings to Table Options menu displays
an empty menu
- [x] Unnecessary spacing under groups
- [x] When no "select" are set on an object, redirect the user directly
to the new Select field page
- [x] Sort : Default should be manual
- [x] Hidding "no value" displays all options and remove the "hide empty
group" toggle
- [x] Hide Empty group option disappeared
- [x] Group by should not be persisted on "Locked/Main view" (**For now
we just disable the group by on main view**)
- [x] Hide Empty group should not be activated by default on
Opportunities Kanban view
- [ ] Animate the group opening/closing (**We'll be done later**)
