[Pomodoro Timer] Timer stops decreasing if system is suspended.

If the system is suspended (say) at the start of the break, the timer stops.

We could sync Pomodoro clock with system clock to fix this.

Start by locating the Pomodoro Timer plugin and its countdown entry point. Reproduce the issue by starting a break, suspending the system, and resuming it; compare the timer with the system clock. Done means the countdown reflects elapsed time after suspension and the existing timer behavior still works during normal use.
