perf: Optimize dashboard queries for faster load times

- Use pg_stat for approximate product count (instant vs full scan)
- LIMIT on DISTINCT queries for brand/category counts
- Single combined query (reduces round trips)
- Add index on store_product_snapshots.captured_at
- Add index on worker_tasks.worker_id and created_at
