feat: enhance selection context menu with alignment options and grouping functionality

- Added alignment buttons for nodes with tooltips in the selection context menu.
- Implemented grouping functionality with a new "Make group" option, including keyboard shortcuts.
- Updated translations for the new grouping feature in multiple languages.
- Refactored node selection logic to improve performance and readability.
