Pull Request Overview

This PR implements a discard changes confirmation dialog for the BookingNoteScreen. When users attempt to navigate back after making unsaved changes to a booking note, they are prompted to confirm whether they want to discard those changes.

Key Changes:

• Implemented back button handling logic that compares current note content with initial state to determine if changes exist
• Added comprehensive test coverage for back button behavior including scenarios with no changes, with changes, during save operations, and dialog interactions
