Refactor database structure and improve player handling.

Reorganized database-related code into a dedicated module, added mappings for UUID handling, and updated SQL queries for clarity. Enhanced team members API to use player data directly, ensuring consistency and better handling of UUIDs. Introduced new database table for connection settings and adjusted Gradle configurations for modularization.
