feat: improve match counting accuracy and efficiency

- Increase match query limit from 50 to 1000 in Settings.get_job_matches/1
- This provides more accurate match counts while maintaining performance
- Match count now shows true available candidates up to 1000
- Existing truncation logic for display still respected based on subscription
- Better reflects actual talent pool size for organizations
