Centralized Error Code Registry

This module provides a single source of truth for all error codes used across Doorman.
Using constants ensures consistency and makes it easier to search/refactor error codes.

Usage:
    from utils.error_codes import ErrorCode

    raise HTTPException(
        status_code=401,
        detail={
            'error_code': ErrorCode.AUTH_INVALID_CREDENTIALS,
            'message': 'Invalid username or password'
        }
    )

    return ResponseModel(
        status_code=404,
        error_code=ErrorCode.USER_NOT_FOUND,
        error_message='User not found'
    ).dict()
