Decouple Dashboard status computation from task queue #1064
Description
Instead of computing status updates on demand whenever a request comes in and computing it via the task queue, maintain the current status and just return it.
Update the status ...
- upon agent initialisation
- after every task execution (as part of the execution).
Technically: Add to SerenaAgent a method _update_status and call it in task execution. The method itself shall call a method in the dashboard (if enabled), which then computes the status as before, albeit without the task queue.
