fix: Decompilation artifact repairs for Java 11 compilation

- Duplicate variable declarations in switch-case branches (AvMenu, ServerInputStream, netData, AnimatedAction)
- Ambiguous null constructor calls requiring explicit casts (ExpireDialog, PosableShape)
- Deprecated getPeer() replaced with isDisplayable() (PolledDialog)
- Decompiler $assertionsDisabled artifact removed (BackgroundLoader)
- Missing null-safety on unboxing (BooleanFieldEditorDialog)
- Raw generic types parameterized (ShallowEnumeration)
- Raw Enumeration cast added (Shape)
