Implement workflow progress panel (#6092)

Adds a workflow progress panel component underneath the
`actionbar-container`.

I suggest starting a review at the extraneous changes that were needed.
Including but not limited to:

- `get createTime()` in queueStore
- `promptIdToWorkflowId`, `initializingPromptIds`, and
`nodeProgressStatesByPrompt` in executionStore
- `create_time` handling in v2ToV1Adapter
- `pointer-events-auto` on ComfyActionbar.vue

The rest of the changes should be contained under
`QueueProgressOverlay.vue`, and has less of a blast radius in case
something goes wrong.
