enhancement: saved-place cards need click-to-locate on the map and a direct delete action

[shauryagangrade]

Problem

Cards in My Places (src/components/map/my-places-panel.tsx:138-164) are plain <div>s whose only affordance is Edit. The whole point of saving a place is finding it again, but there is:

• no click-to-focus on the map (you must open the edit dialog and read coordinates)
• no direct delete (deleting requires opening the editor)

Compare with public results (results-list.tsx), where rows focus the map on click.

Suggested fix

• Make each card clickable to set focusId / fly the map to the pin
• Add a small delete icon-button with confirm/undo (see the destructive-delete issue)
• Keep Edit as a secondary action

Acceptance criteria

• Clicking a saved place focuses it on the map
• A saved place can be deleted without entering edit mode

Fixed in cfe8574. Saved-place cards are now clickable buttons that fly the map to the pin. Inline delete button with confirm/cancel step, no edit dialog needed. Edit remains as secondary action.
