fix: `Accounts_LoginExpiration` being used differently on codebase (#32527)

+
+Fixed an inconsistent evaluation of the `Accounts_LoginExpiration` setting over the codebase. In some places, it was being used as milliseconds while in others as days. Invalid values produced different results. A helper function was created to centralize the setting validation and the proper value being returned to avoid edge cases.
+Negative values may be saved on the settings UI panel but the code will interpret any negative, NaN or 0 value to the default expiration which is 90 days.
