Add record page layout tabs editing (#18702)

- Fix duplication of tabs in dashboards that didn't open the duplicated
tab in the side panel: replaced the logic that used Math.round with an
algorithm that switches the positions of the elements. We will keep
relying on integers, but it will work well in all cases.
- Make dnd work with record page layouts, where there is a pinned tab
- Make tab movements work with pinned tab, too
- Allow user to set a tab as the pinned tab
- Make backend changes to be able to save tabs with `layoutMode`
