fix(web-common): add limit for timeout

[maryliag]

_maxDuration * 1000 and _inactivityTimeout * 1000 can overflow if the config value is large (max safe setTimeout delay is 2147483647, ~24.8 days)
If elapsed time exceeds the max duration possible, setTimeout treats that as 1, firing the reset almost immediately

This PR adds a limit to those values.

You may want to use a constant for the magic number now that there are two instances of 2147483647

nit: add units to the end of the vars (if that is the convention in other files): _MS
