[DataEntry] Migrate from deprecated Grid

[imnasnainaec]

Part of #3787

Notes for review:

• In most places, replaced <Grid> with <Grid2>, <div>, or nothing, as fit the design need.

Notes for testing:

• Do a side-by-side visual comparison between this and master (on QA) to make sure appearance is (roughly) the same or (subjectively) improved on all edited components
• Try each edited component with various window widths > 350px (we don't support narrower than that)
• Test with a few different UI languages
