fix: add missing LayoutRenderingProvider in SettingsApplicationCustomTab (#19679)

## Summary

- `SettingsApplicationCustomTab` renders `FrontComponentRenderer` which
calls `useFrontComponentExecutionContext` →
`useLayoutRenderingContext()`, but the settings page never provided a
`LayoutRenderingProvider`
- Every other render site (side panel, command menu, record pages) wraps
`FrontComponentRenderer` with this provider — it was just missed here
- Opening the "Custom" tab in Settings → Applications crashes with:
`LayoutRenderingContext Context not found`
- Fix: wrap with `LayoutRenderingProvider` using `DASHBOARD` layout type
and no target record, matching the pattern used in
`SidePanelFrontComponentPage`

## Test plan

- [ ] Open Settings → Applications → any app with a custom settings tab
- [ ] Click the "Custom" tab — should render the front component without
crashing
