[Enhancement] Pause timer function

[developersteve]

As a user having a pause function on a timer means i can hit pause for a break without needing to create a whole new time entry by selecting project/client/tag etc again.

Ideally this could also work, and perhaps this is a different ticket, by allowing a few timers to be in a pause state so that the user can unpause as needed.

Solidtime Time Entries always have a start and end timestamp so from a database perspective there is no way to pause a timer, it would always create a new time entry in the database. In the desktop app it is easier to restart the latest time entry as it shows the latest one in the floating mini widget window but i understand it is not that easy in the web app right now.

We will add a Dropdown in the TimeTracker component which shows the most recent time entries and lets you continue those more easily, this is currently in #329. I think this will solve most of the problems related to restarting and pausing time entries.

Other than that I could imagine a Pause functionality that simply stops the time entry and prefills description, project, task, tags etc. again in the UI component.

I'm gonna convert this into a discussion as we handle feature requests in Github Discussions. If anyone has more thoughts on this, feel free to add them below.
