* fix(consumer-prices): restore dropped seed script, fix maxStaleMin
seed-consumer-prices.mjs was included in PR #1901 but accidentally
dropped during a subsequent squash merge. Restored verbatim from the
PR diff. The script fetches from consumer-prices-core and writes all
Redis keys (overview, categories, movers, spread, freshness, series).
Also corrects health.js maxStaleMin values from 2880 (48h) to match
actual seed TTLs: overview/categories/movers=90min, spread=120min,
freshness=30min. The previous values would mask outages for 2 days.
Needs CONSUMER_PRICES_CORE_BASE_URL set in Railway env to produce
real data. Without it the script writes empty-but-valid placeholders.
* fix(consumer-prices): switch publish job to Upstash HTTP REST client
Replaced standard redis TCP client (REDIS_URL → Valkey) with Upstash
HTTP REST calls (UPSTASH_REDIS_REST_URL + UPSTASH_REDIS_REST_TOKEN),
matching the pattern used by all other seed scripts. This is why all
consumer-prices Redis keys were permanently empty — publish.ts was
writing to Railway-internal Valkey instead of Upstash.
Railway env vars added to seed-consumer-prices service separately.
