end_date as a bare date now covers the whole UTC day (23:59:59.999)
instead of stopping at midnight, so end_date=today returns intraday up
to the last closed candle. Dates are parsed as explicit UTC and inline
timestamps (YYYY-MM-DDTHH:MM:SS) are honored for precise windows.
Wide ranges are paged in <=5000-candle windows so Deribit's per-call
cap can no longer silently drop start_date and the oldest candles.
