Fix score refresh, add granular fetch and live job status

Scores never updated ("101d ago"): get_score only recomputes stale/
missing dimensions, but nothing marked them stale on new data, and there
was no scheduled scoring job.
- Fetch endpoint force-recomputes dimensions + composite.
- Scheduled scan (scan_all_tickers) refreshes scores per ticker, so
  scores stay current globally, not just on manual fetch.

Granular fetch: /ingestion/fetch accepts a sources filter; the freshness
bar gets a per-row refresh button (OHLCV/Sentiment/Fundamentals fetch
that provider only — marked paid; S/R/Scores recompute for free). Header
button is now "Fetch All".

Job visibility: GET /jobs/running (any user) + sidebar live indicator
showing running scheduled jobs with progress, polled every 10s.
