[FIX] data validation: handle cell format in auto-complete

[hokolomopo]

Description

The auto complete of data validation showed the raw cell value instead of the formatted value. We should display the formatted value in the auto-complete, but still use the raw value when selecting a proposal.

Task: 4865661

review checklist

• feature is organized in plugin, or UI components
• support of duplicate sheet (deep copy)
• in model/core: ranges are Range object, and can be adapted (adaptRanges)
• in model/UI: ranges are strings (to show the user)
• undo-able commands (uses this.history.update)
• multiuser-able commands (has inverse commands and transformations where needed)
• new/updated/removed commands are documented
• exportable in excel
• translations (_t("qmsdf %s", abc))
• unit tested
• clean commented code
• track breaking changes
• doc is rebuild (npm run doc)
• status is correct in Odoo
