Save which agent is running a task. This is now visible in the admin UI in the queue and in the agent details screen. # changes - [x] save id of agent executing a task - [x] add endpoint to get tasks of an agent for #999 - [x] show assigned agent-id in queue - [x] (offtopic) use same colors for queue stats and icons (similar to the ones used by pipelines) - [x] (offtopic) use badges for queue labels & dependencies
