OpenBar::into_candle and RolledBar::into_candle built their result with
Candle::new_unchecked, skipping the finiteness check. volume is summed
across every absorbed tick/candle, so a long or large run can drift it
to +inf — and an inf-volume candle would silently poison every
downstream indicator.
Switch both to Candle::new, which validates volume finiteness, and
return Result<Candle>. The OHLC fields are finite and correctly ordered
by construction, so the only invariant Candle::new can reject here is a
non-finite volume. push propagates the error with `?`; both flush
methods now return Result<Option<Candle>> and resample_all pulls the
result through.
