feat(measurements): log a resting heart rate by hand

The entry form offered pulse but not resting heart rate, which has its own
chart and series, so a value read off a watch or taken on waking could only
land among spot pulses. The form now offers it next to pulse. The server
already gates the type on the recovery module (its resting_hr domain), so
the form, the dashboard summary, the resting-pulse page, its trend slot and
its correlation channel now follow that module too.
