Fix defer assignment regal lint issue

This PR addresses the Regal lint warnings related to defer-assignment by deferring variable assignments until they are needed. Instead of assigning values upfront, the logic has been updated to perform assignments only when necessary, improving performance and readability. This approach aligns with best practices and ensures consistency across Rego policies.

Reason for Proposed Changes

• Optimize rule performance by deferring assignments until required;
• Ensure compliance with Regal Linter’s defer-assignment rule;
• Improve readability and maintainability by streamlining variable usage.

Proposed Changes

• Refactored variable assignments to only occur when needed;
• Eliminated unnecessary intermediate assignments while maintaining rule logic;
• Ensured all affected files pass Regal Linter without defer-assignment warnings.
