[Fix][Infrastructure UI] Incorrect payload in time range when landing…

… on the Hosts View (#147390)

Closes #146581 

## Summary

This PR fixes the initial `from` date range calculation. The idea is to
convert first the initial range of minutes to milliseconds. Then in
order to get the date of `CALCULATED_DATE_RANGE_TO` - (the calculated
initial range in milliseconds) and call `getTime()` to receive the
calculated `from` date as timestamp.

To test that you can open the host page without the time range in the
URL. Then check the `from` value as in the screenshot attached to the
story and you can use an [Unix timestamp
converter](https://www.unixtimestamp.com/) to verify that the
calculation is correct
