Add hover preview cards

Adds hover-preview UX by introducing preview cards for entities and wiring hoverable links:
- Implements CompanyPreviewCard and ParkPreviewCard components plus hooks to fetch preview data
- Adds HoverCard usage to ParkDetail and RideDetail for operator, manufacturer, and designer links
- Creates preview wrappers for manufacturer/designer/operator links and updates related pages to use hover previews
- Includes supporting updates to query keys and preview hooks to fetch minimal data for previews
