chore: some ui improvements

[richardshiue]

A couple of UI improvements in the grid UI:

• Remove hack for Text overflow with ellipsis is weird and ugly by design flutter/flutter#18761 . Due to the removal of the hack that adds a zero-width space before every single character, the integration test will now find more widgets with the text "Read me", presumably in the sidebar where FlowyText is used. Therefore, I'm changing this findOneWidget to findWidgets.
• Add icons for hide and delete field
  
• Slightly bump up the height of select option editor to make everything in the popup fit by default
• Fixed padding on date and time format buttons

fixes #2761

I created a integration test for creating a option in single select cell. Maybe you can try to add more tests.
