fix(recommender): serve fallback tips to users with no integrations (#117)

The integration-token gate returned 422 for users with no connected
sources, blocking them from any tip. Users with no integrations now go
through the full orchestrator pipeline; if it fails (or returns nothing
because agent outputs are also empty), randomFallbackTip() fires and
serves a generic advice tip instead of an error.
