[IMP] Remove inter module dependency (#274)

This commit introduces significant changes to the architecture of the Horilla HRMS system by decoupling interdependent modules. The following modifications were made:

1. **Module Independence**: Each module has been refactored to eliminate reliance on other modules, promoting a more modular and maintainable codebase.
2. **Refactored Imports and Dependencies**: Adjusted import statements and dependency injections to support independent module operation.
3. **Compatibility and Functionality**: Ensured that all modules are compatible with existing systems and maintain their intended functionality both independently and when integrated with other modules.

These changes enhance the modularity, maintainability, and scalability of the Horilla HRMS, allowing developers to work on individual modules without affecting the entire system. Future development and deployment will be more efficient and less prone to issues arising from tightly coupled code.

**NOTE**
For existing Horilla users, if you face any issues during the migrations, please run the following command and try again the migrations.

- `python3 manage.py makemigrations`
- `python3 manage.py migrate base`
- `python3 manage.py migrate`
