feat: Add Excel, PDF export, and user generation modules

- Implemented `excel_export.py` for generating library item exports in Excel format.
- Created `pdf_export.py` for generating audit reports compliant with DIN 5008 standards, including detailed event tables and signature blocks.
- Developed `generate_user.py` for interactive user creation with validation for usernames and passwords.
- Introduced `module_registry.py` for managing module states and path matching.
- Added a basic `__init__.py` in the `terminplaner` module for initialization.
