Subject: [PATCH] Enhance Phase 1 UI: Layout, Resizer, and Card adjustments

- Changed Phase 1 layout to 2/3 (Lager) and 1/3 (Table) split.

- Added an interactive, draggable resizer handle between the two panes.

- Made Lager cards ~10% wider and enforced a strict uniform height (200px).

- Added manufacturer name to cards and applied text-overflow: ellipsis to prevent line breaks.

- Reduced font sizes for metadata to fit compactly.

- Safely removed SortableJS destroy() logic to prevent JS crash.
