Feature(asr): optimize wizard performance and refactor state management

[Dhara124]

Description

This PR optimizes the Synthetic ASR Wizard's performance and refactors state management to ensure a smoother user experience and robust data preservation. It also synchronizes the branch with the latest upstream changes.

Key Changes

• Performance Optimization: Implemented React.memo and useCallback for all wizard stages (Stages 1-6) to prevent redundant re-renders.
• Improved Dirty Check: Refactored isDirty logic in SyntheticASRWizard.jsx using stable hashing for each stage's data.
• State Preservation: Ensured handleSaveAsDraft and handleNext correctly capture and persist the latest form state.

Verification Plan

• Verified that wizard stages no longer re-render unnecessarily on parent state changes.
• Confirmed that the "Dirty Check" correctly identifies modified data across all wizard stages.
• Validated that drafts are saved and loaded correctly from the backend.
