Add an explicit checkbox to the 'cloud auto synch' status toggle in the
mobile 'Dive Management' menu in order to make it more intuitive to
understand.
This isn't super pretty, but I think it will improve the usability. A
prettier way to achieve this will be to redesign the `ic_cloud_off.svg`
/ `ic_cloud_done.svg` in order to make them intuitively recognisable as
unchecked / checked checkboxes.

implementation: https://groups.google.com/g/subsurface-divelog/c/9X-hTt9NFlE/m/ZcqtdOOhBQAJ
