Dynamically resolve co-op left and right panel UI addresses across index shifts

[AlexanderHel]

Problem

In local co-op mode, the left and right panel paths were previously set to static indices { 22 }\ and { 23 }. However, when temporary or conditional UI elements (such as notification toasts, quest log popups, party overlays, buff bars, or controller HUD elements) load or unload before index 22 in \GameUi.ChildrensPtr, the array positions of the co-op left and right panels shift dynamically to { 21, 22 }\ or { 23, 24 }, breaking panel pointer resolution.

Solution

• Dynamic Window Scanning: Added \UpdateCoopPanelAddresses()\ in \ImportantUiElements.cs\ to scan candidate indices (\20..25) of \GameUi.ChildrensPtr.
• Side Differentiation: Uses \ValidUiElementOrZero\ to validate element self-pointers and compares \RelativePosition.X\ coordinates (where Left Panel X < Right Panel X).
• Fallback Protection: Falls back gracefully to { 22, 23 }\ if dynamic candidate scanning yields no match during UI transitions.
