Allow longer duration than 99 minutes for fallback to preferred sim

Updated firmware to 8.0.2 which fixed the issue of a duration longer than 60 minutes reverting back to 1 minute.

In a situation where one sim is congested tonight on a br1 mini, I’d like to set it to fall back to preferred sim after 300 minutes, as any time it switches it takes a while to reset.

However the UI is only allowing me to enter two digits, a maximum of 99 minutes.

How about allowing longer duration than 99 minutes?
