feat: advance search comopnent, custom directory and breadcrumbs

[rkeerthient]

This was created for an upcoming demo. The package includes:

• An advanced search component with a complete search wrapper (search bar + search results section), supporting individual styling and customizations.
• A custom implementation for a non-address entity type, as required for the demo. This is powered through the Content Endpoint.

PS - No test cases added here.
