Spreadsheet links in Documents now open a helpful popover when users hover over them, making linked content easier to preview and access. The update also adjusts related tests to ensure menus and linked cells continue to behave reliably.

Users can now change the sorting of pivot data sources directly from the spreadsheet interface. The pivot side panel also shows clearer sorting information, including the column used for sorting, and date-based pivot sorting is handled more reliably.

This commit adds a command `UPDATE_PIVOT_SORTING` and a dialog that
allow for an user to edit the sorting of a pivot data source.

Also fix the sorting display in the pivot side panel to display the
column it's sorting on instead of only the measure.

Spreadsheets in Documents now better follow each user's regional settings, such as formatting expectations for different locales. This makes spreadsheet data easier to read and work with for international teams, reducing confusion when users collaborate across regions.
