Remove nginx site accessibility filtering to monitor all sites

- Remove check_site_accessibility function and filtering logic
- Monitor ALL nginx sites from config regardless of current status
- Site status determined by measure_site_latency, not accessibility filter
- Fixes missing git.cmtec.se when backend is down (502 errors)
- Sites with errors now show as failed instead of being filtered out
