Greptile Overview

Greptile Summary

This PR adds location filtering functionality to the new privacy request manager screen. The implementation cleanly integrates a location filter into the existing filter bar infrastructure.

Key changes:

• Extended usePrivacyRequestsFilters hook to manage location filter state with URL synchronization
• Added LocationSelect component to the filter bar UI positioned after the request type filter
• Enhanced LocationSelect component with includeCountryOnlyOptions prop to display both country-only (e.g., "US") and country/region combinations (e.g., "US-CA")
• Backend already supports location filtering via PrivacyRequestFilter.location with proper normalization

The implementation follows existing patterns in the codebase and properly handles URL state synchronization, making filters persistent across page reloads.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The implementation is clean, follows established patterns, and integrates seamlessly with existing infrastructure. The backend already supports location filtering, so this is purely a frontend enhancement. The changes are localized to filter management and UI components without touching core business logic. Type safety is maintained throughout, and the implementation properly handles null values and state synchronization.
• No files require special attention
