DolphinQt: Center dialogs on top-level parent window.
The `QtUtils::AdjustSizeWithinScreen()` function now centers the widget on their parent window after the widget's size is adjusted. This is required in some desktop environments (generally on Linux systems) to ensure that the just-resized widget remains aligned with its parent window. The creation of the **Cheats Manager** dialog is now deferred to first show, as creating it within the main window's constructor prevents the dialog from knowing the real position of its parent window, which is only properly calculated on first show. For the same reasons, the analytics prompt is now shown only when the application is ready (i.e. when the main window has been shown). | Before | After | | ------ | ----- | | <img width="1920" height="1080" alt="[Dolphin Emulator] Misplaced analytics prompt" title="[Dolphin Emulator] Misplaced analytics prompt" src="https://github.com/user-attachments/assets/c3e43b3b-cf79-4398-b531-7de6068c583e" /> | <img width="1920" height="1080" alt="[Dolphin Emulator] Centered analytics prompt" title="[Dolphin Emulator] Centered analytics prompt" src="https://github.com/user-attachments/assets/a10d06d9-7438-4032-b96c-dfcb48826349" /> | | <img width="1920" height="1080" alt="[Dolphin Emulator] Misplaced Settings dialog" title="[Dolphin Emulator] Misplaced Settings dialog" src="https://github.com/user-attachments/assets/f35b10ee-4f07-48d4-86f9-2537ad5ca7ca" /> | <img width="1920" height="1080" alt="[Dolphin Emulator] Centered Settings dialog" title="[Dolphin Emulator] Centered Settings dialog" src="https://github.com/user-attachments/assets/33e37237-77a4-44f6-a0e2-b709f65b672b" /> | | <img width="1920" height="1080" alt="[Dolphin Emulator] Misplaced Cheats Manager dialog" title="[Dolphin Emulator] Misplaced Cheats Manager dialog" src="https://github.com/user-attachments/assets/1fbd3836-5639-4d5a-b57e-e2e21f21c9db" /> | <img width="1920" height="1080" alt="[Dolphin Emulator] Centered Cheats Manager dialog" title="[Dolphin Emulator] Centered Cheats Manager dialog" src="https://github.com/user-attachments/assets/3f2b1b50-de16-49b7-bac4-c444c6cab0bc" /> |
