The text editor's Select All and Undo arms ignored Alt, so a Deselect All
rebound to Cmd+Alt+A or Cmd+Alt+Z was taken as Select All or Undo while a
text edit was open.
The arms now match exactly the chords the editor owns (Cmd/Ctrl+A, and
Cmd/Ctrl+Z with or without Shift); their Alt variants fall through to the
Deselect All binding match. Chords the editor owns still win over a rebound
Deselect All, so Undo keeps working while typing.
Test: a UI kittest rebinds Deselect All to each Alt variant and checks that
Cmd+A and Cmd+Z still edit the text while the rebound chord ends the edit.
