fix: include saved search filters in alert queries (#1882)

HDX-3625

## Summary
- Saved search alerts were ignoring the `filters` field when building the ClickHouse chart config in `getChartConfigFromAlert`
- This caused alerts on saved searches with SQL filters (e.g., `ServiceName IN ('hdx-oss-dev-api')`, `SeverityText IN ('info')`) to evaluate against unfiltered data, producing incorrect alert results
- Added `filters: savedSearch.filters` to the chart config so `renderChartConfig` includes filter conditions in the WHERE clause
