Replace console.log/console.error with proper logger usage in
backupEnvFile and restoreBackup methods. Use the existing 'log' logger
created with createLogger('ConfigManager') following the same pattern
used in other methods.
Changes:
- Import createLogger and create log instance
- Replace console.log with log.debug in backupEnvFile
- Replace console.error with log.error in both methods
- Pass error and path metadata as objects for structured logging
- Fix test to use correct backup path (process.cwd() + src/main/.env.backup)
