feat: Add DatabasesService in services/databases

Implemented new class DatabasesService for handling database interactions in place of multiple database services. This centralizes the interaction with different databases - MariaDb and MongoDB with added logging utility for monitoring query results. Also, a test instance of the DatabasesService was created as 'justForTesting' for development purposes.
