Fix HYPE Polymarket discovery: read its event container

Polymarket now publishes a HYPE monthly event
(what-price-will-hyperliquid-hit-in-{month}, no year suffix), so the
old strike-probe fallback was both unnecessary and mis-ranged -- its
strikes [24..52] predated HYPE roughly doubling to ~$72, so every
"above" market ($76-92) was invisible and all 8 above rows came back
NO POLY. Point HYPE at its event like every other asset and re-range
the probe fallback to the current band [52..92].

Regenerated June pairs.json: HYPE now 16/16 with a Poly leg (was 8/16),
total 110/126 (every non-ZEC row paired; ZEC stays Kalshi-only). Only
HYPE rows changed; the other 7 assets are byte-identical.
