This PR completes the removal of deprecated Dialog props and composed CSS classes, aligning the component API and styling hooks with the slots/slotProps pattern and updated class composition expected for the v9 upgrade path.

Changes:

• Removed deprecated Dialog props: PaperProps, TransitionComponent, and TransitionProps in favor of slotProps.paper, slots.transition, and slotProps.transition.
• Removed deprecated composed CSS utility classes paperScrollPaper / paperScrollBody and updated internal styling/tests/docs to use selectors based on .MuiDialog-scroll* > .MuiDialog-paper.
• Updated API docs, translations, and the v9 upgrade guide with migration instructions and codemod references.
