fix: integration resource listing causing error 5xx

[forestileao]

Summary

Change integration resource listing failures caused by integration/provider state into FailedPrecondition instead of a 5xx.

This prevents third-party integration issues from surfacing as internal server errors when calling:

GET /api/v1/organizations/{id}/integrations/{integration_id}/resources

Changes

• Updated the shared integration resource listing action in pkg/grpc/actions/organizations/list_integration_resources.go
• When an integration's ListResources(...) call fails, the API now:
  • logs the failure
  • returns codes.FailedPrecondition
  • no longer returns a 5xx

Why

Resource listing depends on external integrations and provider-specific configuration.

If an integration is misconfigured, incomplete, disconnected, or a third-party provider fails, that is not an internal SuperPlane server error. Returning FailedPrecondition makes the failure semantics correct and avoids reporting provider/configuration problems as 500-class errors.

Example case:

• Discord channel resource listing failed because the integration was missing botToken
• previously this surfaced as HTTP 500
• now it is treated as a failed precondition instead
