Fetching a symbol the provider doesn't cover (e.g. RHM/Rheinmetall — Alpaca serves US listings only) returned 0 bars but reported "complete · Successfully ingested 0 records", which the UI showed as green success. fetch_and_ingest now returns a distinct `no_data` status when the provider returns nothing AND the ticker has no history (vs. "already up to date" when bars exist). The fetch endpoint maps it to a `warning` source status, and the fetch toast renders it as ⚠ with the provider message instead of success. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
