Enhance input settings and improve UI stability

- Adds a new configurable input action to the settings menu.
- Increases the size of the input mapping list to accommodate more entries.
- Prevents potential crashes by adding a null check when initializing input labels.
- Removes the `INPUT_SHIFT` binding from Lua scripts.
