* feat(feeds): US Natural Gas Storage seeder via EIA (NW2_EPG0_SWO_R48_BCF)

Adds weekly EIA natural gas working gas storage for the Lower-48 states
(series NW2_EPG0_SWO_R48_BCF, in Bcf), mirroring the crude inventories
pattern exactly. Companion dataset to EU gas storage (GIE AGSI+).

- proto: GetNatGasStorage RPC + NatGasStorageWeek message
- seed-economy.mjs: fetchNatGasStorage() in Promise.allSettled, writes
  economic:nat-gas-storage:v1 with 21-day TTL (3x weekly cadence)
- server handler: getNatGasStorage reads seeded key from Redis
- gateway: /api/economic/v1/get-nat-gas-storage → static tier
- health.js: BOOTSTRAP_KEYS + SEED_META (14-day maxStaleMin)
- bootstrap.js: KEYS + SLOW_KEYS
- cache-keys.ts: BOOTSTRAP_CACHE_KEYS + BOOTSTRAP_TIERS (slow)

* feat(feeds): add fetchNatGasStorageRpc consumer in economic service

Adds getHydratedData('natGasStorage') consumer required by bootstrap
key registry test, plus circuit breaker and RPC wrapper mirroring
fetchCrudeInventoriesRpc pattern.
