refactor: extract and streamline EmuReady intent handling

* Moved custom settings logic from `onCreate` to `handleEmuReadyIntent` for better readability.
* Added `showLaunchConfirmationDialog` to confirm game launch with or without custom settings.
* Updated `CustomSettingsHandler.findGameByTitleId` to show user feedback via `Toast`.
* Ensured improved separation of concerns and reusable methods.
