Elie Habib 21d33c4bb5 fix(hyperliquid-flow): fetch both default dex and xyz builder dex (#3077) ...

Root cause: Hyperliquid's commodity and FX perps (xyz:CL, xyz:BRENTOIL,
xyz:GOLD, xyz:SILVER, xyz:PLATINUM, xyz:PALLADIUM, xyz:COPPER, xyz:NATGAS,
xyz:EUR, xyz:JPY) live on a separate 'xyz' builder dex, NOT the default
perp dex. The MIT reference repo listed these with xyz: prefixes but
didn't document that they require {type:metaAndAssetCtxs, dex:xyz} as a
separate POST.

Production symptom (Railway bundle logs 2026-04-14 04:10):
  [Hyperliquid-Flow] SKIPPED: validation failed (empty data)

The seeder polled the default dex only, matched 4 of 14 whitelisted assets
(BTC/ETH/SOL/PAXG), and validateFn rejected snapshots with <12 assets.
Seed-meta was refreshed on the skipped path so health stayed OK but
market:hyperliquid:flow:v1 was never written.

Fix:
- New fetchAllMetaAndCtxs(): parallel-fetches both dexes and merges
  {universe, assetCtxs} by concatenation. xyz entries already carry the
  xyz: prefix in their universe names.
- New validateDexPayload(raw, dexLabel, minUniverse): per-dex floor so the
  thinner xyz dex (~63 entries) does not false-trip the default floor of
  50. Errors include the dex label for debuggability.
- validateUpstream(): back-compat wrapper — accepts either the legacy
  single-dex [meta, assetCtxs] tuple (buildSnapshot tests) or the merged
  {universe, assetCtxs} shape from fetchAllMetaAndCtxs.

Tests: 37/37 green. New tests cover dual-dex fetch merge, cross-dex error
propagation, xyz floor accept/reject, and merged-shape pass-through.
