Standardize on Named Exports Throughout Codebase

[prasadhonrao]

Description

Convert all default exports to named exports for consistency and better tree-shaking.

Current State

Mixed use of default and named exports:

• export default config in config.js
• export default logger in logger.js
• Named exports in controllers

Proposed Solution

Use named exports consistently:

// Before
export default config;

// After
export { config };
export default config; // Keep for backward compatibility initially

Benefits

• Better tree-shaking in bundlers
• Clearer import statements
• Prevents naming conflicts
• Easier refactoring

Priority

Medium - Code consistency improvement
