feat(platform): custom agents empty state, skeleton, and toggle improvements

[Israeltheminer]

Summary

• Add empty state and loading skeleton for the custom agents page
• Improve active toggle to handle draft agents with published versions (re-publish instead of activate)
• Auto-initialize AI assistant thread when creating automations with a description
• Minor UI fixes (automations empty state padding, vendor details label)

Test plan

• Verify custom agents page shows skeleton while loading
• Verify custom agents page shows empty state when no agents exist
• Verify toggling a draft agent with prior published versions calls publish
• Verify creating an automation with a description initializes an AI thread
• Run existing custom agent toggle tests

📝 Walkthrough

Walkthrough

This PR integrates AI-assisted workflow creation into the automation flow and enhances custom agents functionality. It adds a chat thread creation mechanism triggered after automation creation, updates automation metadata with thread IDs, and invokes a workflow assistant with an initial prompt. The custom agents feature gains new empty-state and skeleton UI components, and the active-toggle component now handles agent publishing in addition to version activation. Related routes conditionally render loading and empty states. Translations are added for custom agent empty states and automation initialization prompts.

35-44: 🧹 Nitpick | 🔵 Trivial

Consider removing the redundant isLoading prop.

Since the loading state is handled by the early return on line 19, isLoading will always be false when CustomAgentTable renders. Consider removing this prop if it's not needed by the table component.

♻️ Proposed refactor

   return (
     <ContentWrapper>
       <CustomAgentTable
         organizationId={organizationId}
         agents={agents}
-        isLoading={isLoading}
         collection={customAgentCollection}
       />
     </ContentWrapper>
   );
