fix(ingestion): make the pipeline actually run against live feeds

First end-to-end run against Postgres and the real government APIs, which
surfaced four defects that static checks could not.

- Agmarknet pointed at 9ef84268-…, "Current Daily Price": a today-only
  snapshot holding one arrival_date, in which none of the four pilot
  districts appear. Switched to 35985678-…, the historical resource.
- Filter fields were lowercase. This resource matches exactly on the
  capitalised name; the lowercase form is tokenised, so "Madhya Pradesh"
  also matched Andhra, Himachal and Uttar Pradesh — wrong-state prices
  written under a pilot district, with freshness looking healthy.
- Rows arrive unordered and the lookback filter is client side, so a page
  was mostly years-old data and every commodity wrote zero weeks. Added
  sort[Arrival_Date]=desc.
- ExternalFeedConfig injected a RestClient.Builder bean Boot does not
  expose, so the context never built and the app could not start.

Also: Open-Meteo meters by request cost, so the 30-year baseline call
exhausted the minutely allowance and 429'd two districts out of their
climate data. Rate-limited calls now retry with backoff, while genuine
failures still fail once and are reported.

FODDER moves to MANUAL — Agmarknet carries Green Fodder, but every recent
row is a single market in Ambala, Haryana.

Result: 16,000 rows fetched, 202 market weeks and 52 climate weeks written,
0 failed calls; 142 scored, 33 trip-wires fired.
