feat: Add software licenses management page and update payment handling

- Introduced a new licenses management page with functionality to create, update, and view software licenses.
- Updated payment return handling in softwaretool.php to check payment status from the database and display appropriate modals for success, pending, and failure states.
- Enhanced webhook_mollie.php to log webhook calls, handle payment status updates directly in the database, and generate invoices based on payment status.
- Improved CSS styles for better alignment of buttons and modal components.
- Added JavaScript for modal interactions and bulk license creation functionality.
