BUG: Ctrl + A selects sidebar items instead of all items on the board

When pressing Ctrl + A on the keyboard, instead of selecting all items on the board (sticky notes, cards, text boxes, etc.), Noteey incorrectly selects elements from the sidebar and triggers Arrow/Linking mode.

This behavior is inconsistent with standard keyboard shortcuts.
The Ctrl + A shortcut should only select all items on the board, allowing users to quickly delete, move, or copy multiple items at once.

Currently, it seems Noteey interprets the combination Ctrl + A the same way as pressing A alone — which should only activate the Arrow or Linking tool.

Expected behavior:

• When pressing Ctrl + A, only items on the main board should be selected.

• Pressing A (without Ctrl) should continue to activate the Arrow/Linking tool.

• Sidebar elements should not be affected by Ctrl + A at all.

This issue makes it difficult to manage multiple objects efficiently and interrupts the expected keyboard workflow.
