Kalshi API prices live in *_dollars fields, not yes_bid

The public, unauthenticated endpoint https://api.elections.kalshi.com/trade-api/v2/markets?series_ticker=KXALIENS&status=open&limit=5 returned None for yes_bid and yes_ask, which looks like a market with no quotes. The prices were in string fields: yes_bid_dollars, yes_ask_dollars and last_price_dollars (e.g. '0.2400' = 24% implied odds). Read those fields instead. Querying by guessed series_ticker values (KXALIENS, for example) is a quick way to find a specific market. A third-party listicle of odd Kalshi markets returned 403 to WebFetch, so the API was the more reliable source.
