fix(market): Handle empty agents response

[Abhi1992002]

Fixes #8370

I added a check to handle cases where no agents or featured agents are returned from the backend. This prevents the marketplace from crashing due to an undefined property error and ensures the UI still loads properly.

Changes 🏗️

Added fallback messages for when featuredAgents and topAgents are empty.

⚡ Recommended focus areas for review Potential Bug The change on line 121 assumes that agent.categories is always defined. This might cause issues if categories is undefined for some agents. Code Duplication The messages for "No Featured Agents found" and "No Top Downloaded Agents found" are very similar. Consider extracting this into a reusable component to reduce duplication.

@Abhi1992002 thanks for this, but the supabase submodule shouldn't be deleted in this PR. Can you please fix that?
