perf(cfdi): optimize page performance

Database optimizations:
- Add indexes on fecha_emision, tipo, estado, rfc_emisor, rfc_receptor
- Add trigram indexes for fast ILIKE searches on nombre fields
- Combine COUNT with main query using window function (1 query instead of 2)

Frontend optimizations:
- Add 300ms debounce to autocomplete searches
- Add staleTime (30s) and gcTime (5min) to useCfdis hook
- Reduce unnecessary API calls on every keystroke
