feature request: standardize time units

[ggomarighetti]

What problem did you meet?

The time units, more specifically, the access-token and refresh-token units differ, the former being in "seconds" and the latter in "days". Using different scales or time measurements for something that perhaps should or could be standardized.

Describe what you'd like Logto to have

I propose either to adapt a standardized unit of time, such as the seconds used in the access token, or, as a more complex alternative, to leave the validation only of integers and add formatting to the values using day, hour, minute, second, for example, that the end user enters in the Logto console "1d12h30m30s" equivalent in an integer value to 131430 seconds.

Good suggestion! I'll discuss with the team.
