Cases/redesign filters and list [1/2]

[MykhailoKondrat]

What & Why

Refactors the cases_redesign directory to keep only new/modified files needed for the redesigned All Cases page. Introduces a list view mode as an alternative to the existing table view — users can toggle between a card-based list and the traditional table via a persisted EuiButtonGroup toggle. The list view displays case metadata (assignees, severity, status, alerts, reporter, last updated) in a compact card layout with configurable optional fields, providing a scannable alternative to the dense table.
New header integration, list view sorting and other minor updates will be added in a following PR.

How to Test

1. Enable the cases redesign feature flag and navigate to the All Cases page. xpack.cases.casesRedesign.list: true
2. Verify the view toggle (list/table icons) appears in the filter bar and defaults to "List view."
3. Switch between list and table modes — confirm the preference persists across page reloads (stored in local storage).
4. In list mode, open the "Fields" popover and toggle optional fields on/off — confirm the list items update accordingly.
5. In selector/modal contexts, confirm the toggle is hidden and the table view is always used.
