fix(platform): Make LibraryAgent image as initial StoreListing image

Changes 🏗️

We've been auto-generating the thumbnail image for the agent in the library, this PR is propagating that image as an initial image for the store listing. This PR also removes the fetch all query for getting the count for paginating library agent.

⚡ Recommended focus areas for review Parameter Mismatch The function call to generate_agent_image has been updated to use 'graph' as parameter name, but the function signature in image_gen.py expects 'agent'. This could cause confusion or errors. image = await store_image_gen.generate_agent_image(graph) Fallback Image The code still uses a hardcoded fallback image URL (picsum.photos) when agent_image is null. Consider using a more appropriate default image or handling this case differently. imageSrc: agent.agent_image || "https://picsum.photos/300/200",
