Issue: Refactor Configuration and Database Files to ES6 Module Syntax

[agaesh]

Description:
As part of the ES6 migration initiative, we need to refactor the configuration and database setup files to use ES6 module syntax instead of CommonJS. This ensures consistency across the codebase and improves maintainability and readability.

Tasks:

• Convert all require statements to import syntax.
• Replace module.exports with export default or named exports where appropriate.
• Reorganize and optimize imports for clarity and maintainability.
• Add or update inline comments to improve readability.
• Remove redundant or outdated configuration logic.

Notes:

• No functional changes are expected — this refactor focuses solely on syntax modernization.
• Testing for these changes will be handled later in the ES6 integration testing phase.

Motivation:
This task is part of the broader ES6 modernization effort to improve code consistency, maintainability, and scalability across the entire codebase.
