Summary

Fixes #515: bare GET /api/v1/oracle/price returned USTC/USD (~0.005) while integrators treated it as LUNC/USD (~0.00005) — exact ~100× overstatement.
Breaking v1 (approved): /api/v1/oracle/price and /history return a ticker catalog; snapshots live at /price/{ustc|lunc} and /history/{ticker}.
Poller fetches both tickers with distinct CEX/CoinGecko symbols into ticker-scoped oracle_prices; volume USD still uses USTC only.
Docs/invariants X1–X6, runbook, agent skill, and make verify-issue-515.

Test plan

make verify-issue-515 (docs + cargo test --lib oracle + api_oracle + frontend Protocol/Trade)
Retest: lib oracle + api_oracle after verify
Deploy indexer migration on staging/prod; confirm /api/v1/oracle/price returns catalog only
Compare /price/lunc vs live KuCoin/MEXC LUNCUSDT within same minute
Compare /price/ustc vs USTCUSDT (should stay ~0.005-scale, not LUNC-scale)
Protocol page still shows USTC/USD via default getOraclePrice()

Closes #515
