Add option to Pause and Resume events during task breaks

Sometimes I need to take a short break during a task—whether it's for a quick call, a bio break, or a mental refresh. Currently, there is no option to pause an event in Yappa and then resume it upon returning to the task. Adding a “Pause” and “Resume” feature would be helpful for accurately tracking time spent on each task and managing unexpected interruptions without ending the event prematurely.
