fix: disable global keybindings while a modal dialog is open

Gate keybindHandler on dialogStore.dialogStack so background shortcuts
no longer fire when a modal (e.g. Templates) is open. Keybindings whose
event target is inside the dialog still execute, preserving dialog-scoped
shortcuts.

Fixes FE-642
