consolidate navigation state handling

[ash1shkumar]

📝 Description

This PR improves navigation state coordination by introducing a centralized navigation state helper for sidebar route management.

Previously, active navigation state determination and styling logic were handled directly within component rendering. As navigation flows and application layouts expand, maintaining consistent behavior across navigation interactions can become increasingly difficult.

Changes Implemented

• Introduced a reusable navigation state helper
• Centralized active route determination logic
• Consolidated navigation styling decisions
• Reduced duplicated navigation state calculations
• Improved separation between navigation logic and rendering
• Enhanced maintainability of sidebar navigation workflows

Benefits

• Improved navigation consistency
• Reduced synchronization complexity
• Easier maintenance of navigation behavior
• Cleaner component structure
• Better scalability for future navigation features
• More predictable route state handling

🎯 Type of Change

• Refactoring
• Code Quality Improvement
• Maintainability Enhancement

✅ Testing

• Verified active route highlighting remains accurate
• Verified navigation links function correctly
• Verified sidebar rendering remains unchanged
• Verified route transitions work as expected
• Verified navigation styling behavior remains consistent
• Verified no regressions across existing navigation flows

Fixes #214
