The vchan setRigFrequency wrapper was awaiting vchanTakeSchedulerControl() (HTTP PUT to /scheduler-control) and vchanSetChannelFreq() (HTTP PUT to channel freq endpoint) before calling the original setRigFrequency. This added a full HTTP round-trip of latency to every frequency change. Make both fire-and-forget: optimistic local update happens first, network calls run in background.
