fix: improve command palette actions and automation condition button

- Action items (start/stop, enable/disable) no longer close the palette
- Action items toggle state after success (Start→Stop, Enable→Disable)
- Toast z-index raised above command palette backdrop (3000→3500)
- Automation condition remove button uses ICON_TRASH SVG instead of ✕
