refactor(update-backend): reorder permission settings and update migration message

- Moved permission setting commands to the end of the script for better clarity and execution flow.
- Changed the log message from "Running database synchronization..." to "Running database migrations..." to accurately reflect the operation being performed.
- Ensured that permission settings for backend and data directories are consistently applied after the migration process.
