fix(front): focus new Field widget and open side panel on add (#20777)

## Context
In the record-page edit mode, the "Add widget" section has three menu
items:
`Fields group`, `Field`, and `More widgets`. `Fields group` creates the
widget, focuses it, and opens its settings side panel. `Field` only
added the widget to the draft — no focus, no panel — which left the user
without visible confirmation or a way to immediately edit the new
widget.

## Change
Updated `useCreateRecordPageFieldWidget` to mirror
`useCreateRecordPageFieldsWidget`:
After appending the new widget to the draft, it now sets
`pageLayoutEditingWidgetIdComponentState` to the new widget's id and
navigates the side panel to `SidePanelPages.RecordPageFieldSettings`
(with `focusTitleInput: true`, `resetNavigationStack: true`).
This matches the behavior of clicking an existing field widget in
`useOpenWidgetSettingsInSidePanel` (`WidgetType.FIELD` branch).
