fix(frontend/marketplace): prevent agent page crash on 404

[seer-by-sentry]

Why / What / How

The agent marketplace page (/(platform)/marketplace/agent/[creator]/[slug]) previously crashed with an ApiError when attempting to load a non-existent agent. This was due to getV2GetSpecificAgent() being called in both generateMetadata() and the main page component without proper error handling for 404 responses.

This PR implements a try/catch block around calls to getV2GetSpecificAgent() to gracefully handle 404 ApiError responses.

If an ApiError with a 404 status is caught, notFound() from next/navigation is called, ensuring the page renders a 404 page instead of crashing. This pattern mirrors the existing robust error handling found in the sibling creator page (/(platform)/marketplace/creator/[creator]/page.tsx).

Changes 🏗️

• Added try/catch blocks around calls to getV2GetSpecificAgent() within generateMetadata() and the main page component for /(platform)/marketplace/agent/[creator]/[slug].
• Implemented notFound() from next/navigation to be called when a 404 ApiError is caught from getV2GetSpecificAgent().

• I have tested my changes according to the test plan:
  • Navigate to /(platform)/marketplace/agent/[creator]/[slug] with a valid agent slug and confirm the page loads correctly.
