add OnlyIfNotExists alert suppression feature
Adds ability to suppress alerts during maintenance windows by checking
for the existence of a file. When the file exists and is recent (within
configured max age), matching alerts are excluded from email reports.
Features:
- Global PrometheusOnlyIfNotExists config for Prometheus alerts
- Per-check OnlyIfNotExists config for individual checks
- Configurable max age (default 86400s) for suppression file
- New "Suppressed alerts" section in email and HTML reports
- Suppressed checks excluded from counts and unhandled sections
