More performant /historical/intraday endpoint

First page response time is faster: 95% of requests on the first page now complete under 100ms, even under much heavier load.
5x the rate limit: you can now make up to 1,000 requests a minute, up from 200 on this endpoint.
Page size limit: the maximum pageSize is now 1,000. We reject any request above that, which keeps the service up more reliably for everyone.
