feat(editor): streamline cell editing and navigation with improved keyboard support (#12770)

https://github.com/user-attachments/assets/6bce5fa3-fb25-4906-bef1-50d4da4a13f6

This PR addresses #12769 and improves table editing UX by making Enter
commit changes and move focus down, and Tab/Shift+Tab move focus
horizontally—matching spreadsheet-like behavior.

Typing now immediately enters edit mode for selected cells without
double-clicking.
These updates apply to both the standard and virtual table views.
