Several issues occur when using LeanType with a physical keyboard

Describe the bug

Several issues occur when using LeanType with a physical keyboard:

• "Ctrl + Space" crashes LeanType instead of switching language.
• "Shift + Space" does nothing.
• There is no working shortcut to open the emoji panel using the physical keyboard.
• When "Show toolbar with physical keyboard" is enabled, the toolbar appears empty.
• There is no way to assign custom shortcuts for actions such as opening the clipboard without showing the virtual keyboard.

To Reproduce

1. Connect a physical keyboard to an Android device.
2. Enable multiple languages in LeanType.
3. Start typing in any text field.
4. Press "Ctrl + Space" → LeanType crashes.
5. Press "Shift + Space" → nothing happens.
6. Enable the physical keyboard toolbar → the toolbar appears empty.
7. Try to access emoji or clipboard without opening the virtual keyboard → there is no physical-keyboard shortcut.

Expected behavior

Physical keyboard users should be able to access common LeanType actions without having to show or touch the virtual keyboard.

In particular, language switching should have a working shortcut, and actions such as emoji and clipboard should be accessible through configurable physical-keyboard shortcuts.

It would also be useful to allow users to assign their own shortcuts, for example:

"Alt + E" → Emoji
"Alt + C" → Clipboard
"Ctrl + Space" → Switch language

The clipboard should be able to open and be navigated with the physical keyboard while keeping the virtual keyboard hidden.
