Improved onCellFocused to check if already editing same cell before starting edit mode.
Problem: Enter key moves to next cell + startEditingCell(), then onCellFocused fires
and tries to startEditingCell() again on same cell, causing timing issues.
Solution: Check getEditingCell() to see if we're already editing the focused cell
- If same cell: skip (already editing)
- If different cell: enter edit mode
Result: Enter key → next cell → auto edit mode (no duplication)
Tab/Click/Arrow → auto edit mode (only once)
