Subject: [PATCH] feat(proto): upgrade price.proto float to double for
 multi-currency precision

Changes PriceResponse.price from float (32-bit, ~7 sig figs) to double
(64-bit, ~15 sig figs) to avoid silent truncation of JMD and other
non-USD fiat exchange rates that need >7 significant digits.

Wire-compatible: protobuf handles float->double conversion transparently.
