fix(GUIMove): restrict Inventory mode to container screens and respect skip() for key suppression

[Eccys]

Type of change

• Bug fix
• New feature

Description

1. In GUIMove.skip(), Screens.Inventory previously only skipped WidgetScreen (along with the hardcoded text-input screens), allowing movement and rotation in non-inventory screens such as PauseScreen (the Escape menu), AdvancementsScreen, BookEditScreen, and HangingSignEditScreen. Updated skip() so Screens.Inventory requires AbstractContainerScreen<?>, Screens.Both requires WidgetScreen || AbstractContainerScreen<?>, and SignEditScreen is broadened to AbstractSignEditScreen.
2. Added && !skip() to disableSpace() and disableArrows() so ScreenMixin.onKeyPressed does not swallow Space or Arrow keys in skipped screens (such as AnvilScreen, the Creative search tab, sign/book edit screens, or WidgetScreen when guis is set to Inventory).

How Has This Been Tested?

Verified compilation against Minecraft 26.2 (./gradlew compileJava) and tested skip(), disableSpace(), and disableArrows() across GUI, Inventory, and Both modes.
