feat(train): the Loop's live heart rate in a recording (ADR 0030, D41)

Browse source 
A recording with a Loop set up reads its heart rate through Polar's SDK
while no strap sends: the strap first, the Loop where there is none or
while it is lost. The SDK is one for the process, held by the open
app's bridge and by the recording service, so that the band stays
connected with the app gone; the app reopening finds it connected. The
recording file gains `loop` state lines; the rate is kept alone, as `h`
lines, and the Record sheet names the source.
