Undo behavior for auto-added table rows

[bcmeireles]

Summary

Fixes table-view row undo behavior for auto-added rows created after pressing Enter on the last row title.

This PR ensures:

1. For a newly auto-added row with empty, untouched title:

   • Esc removes the row
   • Enter removes the row
   • Ctrl/Cmd+Z removes the row

2. If the user typed in the new row title first:

   • Esc only cancels/reverts title editing behavior and does not remove the row
   • Ctrl/Cmd+Z removes the added row/card (undo at board level)

Fixes #4849

Manual Test Coverage

• Create auto-added row via Enter on last row title.
• Esc on untouched empty auto-added row removes it.
• Enter on untouched empty auto-added row removes it.
• Ctrl/Cmd+Z on untouched empty auto-added row removes it.
• After typing in new row title, Esc does not remove the row.
• After typing in new row title, Ctrl/Cmd+Z removes the added row.
