## Summary
This PR updates the alert editor forms with
1. A history of alert states
2. An option to Ack/Silence an alert that is firing
The components and much of the new GET /alert/:id endpoint are shared with the existing alert page functionality.

## Summary
This PR implements alerting on Raw SQL-based line/bar charts.
- This is only available for line/bar charts with this change. Number charts will be added in a future PR.
- The threshold is compared to the _last_ numeric column in each result.
- The interval parameter must be used. This is required for line charts to function, and is used for zero-fill and other functionality within the alerts task. This limitation will be removed for Number chart alerts when those are implemented.
- Start and and end date should be used, but are not required because there are some potential use-cases where they may not be desirable.

## Summary
Upgrade all `@mantine/*` packages from v7.17.8 to v9.0.0 (skipping the v8 intermediate step since the breaking changes were manageable in a single pass). This improves React 19 compatibility and keeps the UI library current.
### Breaking changes resolved
**v7 → v8 changes:**
- `DateTimePicker`/`DateInput` `onChange` now returns a date string instead of a `Date` object — updated handlers in `AlertScheduleFields.tsx` and `SourceForm.tsx`
- Updated `postcss-preset-mantine` to ^1.18.0
**v8 → v9 changes:**
- `Collapse`: renamed `in` prop to `expanded` (11 instances across 10 files)
- `Grid`: removed deprecated `overflow="hidden"` prop (5 instances, 3 files) — v9 uses native CSS `gap` instead of negative margins
- `Text`/`Anchor`: renamed `color` prop to `c` style prop (7 instances, 5 files)
- `SourceSchemaPreview`: replaced removed `TextProps` `color` key with `React.CSSProperties`
- Theme: set `defaultRadius: 'sm'` in both theme configs to preserve existing visual appearance (v9 changed default from `sm` to `md`)
- Updated test for Collapse visibility behavior change in jsdom
### Not affected (verified)
- No `@mantine/carousel` or `@mantine/tiptap` usage — embla and Tiptap migrations not needed
- No `TypographyStylesProvider`, `Spoiler`, `positionDependencies`, `useFullscreen`, `useMouse`, `useMutationObserver`, or `zodResolver` from `@mantine/form` usage
- All `useLocalStorage` calls from `@mantine/hooks` already provide `defaultValue`
- `react-hook-form-mantine` has a peer dep mismatch (expects `@mantine/core ^7.0.0`) but its thin wrappers are compatible at runtime
### How to test locally or on Vercel
1. Start the dev stack with `yarn dev`
2. Navigate through key pages: search, dashboards, alerts, services dashboard, Kubernetes pages
3. Verify Collapse animations work correctly (alert details, nav sub-menus, advanced settings)
4. Verify Grid layouts render properly on services dashboard side panels
5. Verify no visual regressions in border-radius, spacing, or color across components

## Summary
This PR extracts a TileAlertEditor component for future re-use in the Raw-SQL Alert UI. The UI has been updated to make the alert section collapsible and co-locate the "Remove Alert" button within the alert section. The collapsibility will be more important in the Raw SQL case, since the Raw SQL Editor is already pretty vertically tall.
