Improve image handling, optimize hooks, and add rate limiting

This commit introduces several improvements:
- Enhances `RideModelCard` by safely accessing and displaying ride count and image data, preventing potential errors.
- Refactors `useEntityVersions` and `useSearch` hooks to use `useCallback` and improve performance and prevent race conditions.
- Introduces a `MAX_MAP_SIZE` and cleanup mechanism for the rate limiting map in `detect-location` Supabase function to prevent memory leaks.
- Adds robust error handling and cleanup for image uploads in `uploadPendingImages`.
- Modifies `ManufacturerModels` to correctly map and display ride counts.
- Includes error handling for topological sort in `process-selective-approval` Supabase function.
