cmd: date: validate date using rtc_month_days()

The old check accepted day 0 as well as Feb 29th in non-leap years.
With this change, both day and month 0 are rejected, and the local day
limit logic is now handled by rtc_month_days(), which correctly accounts
for month length and leap years.

In the 'MMDDhhmm' format case, tm_year is not initialized by mk_date().
The leap-year calculation in rtc_month_days() therefore depends on the
value provided by the caller, which do_date() does, via dm_rtc_get().
This is pre-existing behaviour, but is now made more explicit.
