H-1323: Add /workers page, update flow run routes

[CiaranMn]

🌟 What is the purpose of this PR?

The PR introduces a /workers page which lists all active worker runs. These may be 'goals' which are research-driven flows (the /goals page to be introduced in the next PR), or other flows.

It also updates the routes for viewing:

1. Flow definitions to /@[namespace]/flows/[id]
2. Worker runs (flows or goals) to /@[namespace]/workers/[id]

These routes have essentially the same UI for now so they share a component. I've also updated the context providers so that we poll for all flow runs with fewer details (that doesn't require the event history) on a slower schedule, and the single selected flow run more frequently.

Thanks Ciaran, these changes look good to me 👍

[benwerner01]

Maybe we can discuss this internally rather than in a thread, but these outputs have been useful for me in the past when debugging errors in flows - but it makes sense to remove them if they're leading to the flow not being failed correctly.

I suppose I can use the getFlowRuns resolver in the meantime.

[CiaranMn]

I can actually restore these, I thought it was causing temporal to not fail but it's actually because I wasn't using their special ApplicationError (added in the follow up goals PR)

[CiaranMn]

I did this in the next PR, b211df2

[benwerner01]

Gotcha, thanks!

The base branch was changed.
