[atlas] Minor nit in first monthly probe report after registration

Resent, hopefully without HTML formatting this time (sorry for earlier)

Hi,

A minor nit with regards to the availability time in the monthly probe report for the month the probe was registered in:

The total availability indicated is bogus as the whole month is taken as the calculation interval as its basis, rather than only the time since probe registration.

Calculation interval : 2024-06-01 00:00:00 - 2024-07-01 00:00:00
Total Connected Time : 0d 14:40
Total Disconnected Time : 29d 09:19
Total Availability : 2.04%

I guess just an optical issue rather than a problem, maybe a bit misleading. The UI seems to take the fractional aspect into account, which seems more relevant.
