fix(platform): Restore See runs button on marketplace listing page (#9970)

This makes button on the marketplace listing page show `See runs` if
user has an agent in the library.

### Changes 🏗️

- Remove `/` from the related endpoint
- Use `active_version_id` instead of `store_listing_version_id` to check
for the library agent
- Fix `get_store_agent_details`
