View panels: faster loading, sharing, and safer layout

• ✓ Lazy-loaded panels so views open faster
• ✓ Archive or delete panels from the menu; mapping overlay when placing cards
• ✓ Resize and layout fixes for more predictable panels

Views feel snappier and easier to share: panels load when you need them, presets can be captured as short links, and day-to-day management (archive, delete, mapping topics into a panel) is more explicit.

• View panels use lazy Turbo loading to defer work until a panel is shown

• Table presets can expose a short code for shareable snapshot-style links

• Archive or remove panels from the dropdown; mapping topic cards shows a dedicated overlay

• Sizing, shadows, and resize behaviour refinements for steadier layouts
