Refactor SIM management and usage services for improved functionality and type safety

- Updated SimManagementService to schedule plan changes for immediate execution during testing.
- Enhanced type safety in SimUsageStoreService by removing unsafe type assertions and improving method calls.
- Improved error handling in FreebititService by ensuring proper type handling for plan codes and sizes.
- Added functionality in manage.sh to automatically find and assign free ports for development services.
