zeekay 4532862f22 fix: use query-param format for crypto bars (sandbox single path 404s) ...

Same issue as snapshots — Alpaca sandbox returns 404 for
/v1beta3/crypto/us/{sym}/bars but works with
/v1beta3/crypto/us/bars?symbols={sym}. Also handle the wrapped
response format {"bars":{"BTC/USD":[...]}} vs stock {"bars":[...]}.
