Summary

• group the integrations list into accordions by type, including the new “Custom OAuth” section, while keeping counts and total displayed in the header
• simplify the provider display logic and preserve the existing connect/disconnect behavior inside the new collapsibles
• ensure the feed keeps its cached hook usage so no additional API calls were introduced beyond the existing parameters

Testing

• Not run (not requested)

Summary by cubic

Refactored the Integrations page to group providers into collapsible sections by type (including Custom OAuth) and added a filtered count in the header. Preserved connect/configure/reconnect/disconnect flows and reduced redundant API calls with better caching.

• New Features

  • Group integrations into accordions: Built-in credentials, OAuth, Custom OAuth, MCP, Custom MCP.
  • Keep “Custom OAuth” visible even when empty; each section shows its item count.
  • Simplified item rendering and click behavior; configured state and environment badges are shown consistently.

• Performance

  • Added React Query caching (5-minute stale time, no refetch on focus) for integrations, providers, MCP list/get, and provider details/schema.
  • Maintains existing feed caching; no new API calls beyond current parameters.
