feat(bisaya-course): update lesson retrieval and didactics processing

- Refactored the lesson retrieval logic to include lesson number and title in the query, improving data handling.
- Updated the didactics processing to utilize a lesson-like object instead of fetching lessons by primary key, enhancing performance.
- Improved error handling and ensured proper closure of the database connection after execution.
