Apparently I didn't use my brain cells and rely on the /version
endpoint that Headscale has exposed since 0.26 (our lowest supported
version). Switching to that significantly simplifies the API surface.
Previously we would use naive revalidators which would invalidate EVERY
SINGLE action loader every 3 seconds, resulting in several fetches. It
would also bubble fetches across the layout actions into the individual
pages.
This new approach selectively has live stores of resources which then
poll for changes on the server side and then dispatches updates to the
client via a new /events/live SSE endpoint.
