* Fix Mangabaka dates drifting in negative timezones
This was only partially handled in #3047, but MB returns full datetime
strings with a truncated time component that's always midnight UTC.
So when Mihon then parses the returned dates, it gets the day wrong in
any negative offset timezones.
With this, Mihon now discards the time component and instead takes the
date component + start-of-day in the device timezone.
