Refactor pre-commit hooks to manual execution, enhance uptime monitoring with new models and batching notifications

- Updated .pre-commit-config.yaml to change hooks to manual execution for performance.
- Added UptimeHost and UptimeNotificationEvent models to support host-level monitoring.
- Enhanced UptimeService to batch notifications for multiple service failures on the same host.
- Implemented tests for notification batching and uptime host creation during sync.
- Improved formatDuration function for better readability of durations.
