feat: Create dedicated OpenTuna installer page

This commit introduces a new, separate menu page for the OpenTuna installer, accessible by navigating right from the main menu.

The new page includes two options:
- Install OpenTuna
- Uninstall OpenTuna

The necessary UI strings, menu items, and event handlers have been added. The navigation logic has been updated to create a circular flow between the main menu, OpenTuna menu, MC menu, and extras menu.

Additionally, a bug in the main menu loop has been fixed where pressing the cancel button (circle) would exit the application instead of navigating back. The menu execution logic now correctly handles this as a "back" action.

The ROM version of the console is now also displayed on the OpenTuna installer page.
