fix: suppress noisy health check logs in production
Add logger filter to drop Kubernetes health probe logs that were flooding
production logs every few seconds.

Implementation:
- Create ToweropsWeb.TelemetryFilter module with filter_health_checks/2
- Configure as logger :default_handler filter in prod.exs
- Filters based on request_path metadata and message content
- Drops logs for GET /health and HEAD / requests

Impact:
- Eliminates ~120 log entries per minute per pod from K8s probes
- Keeps application logs focused on actual user activity and errors
- No impact on health check functionality - only suppresses logging

Files:
- lib/towerops_web/telemetry_filter.ex (new)
- lib/towerops/application.ex (attach filter on startup)
- config/prod.exs (add filter to logger config)
- CHANGELOG.txt
