Auto-update the system status in admin dashboard (#29163)
- Refactor the system status list into its own template
- Change the backend to return only the system status if htmx initiated
the request
- `hx-get="{{$.Link}}/system_status`: reuse the backend handler
- `hx-swap="innerHTML"`: replace the `<div>`'s innerHTML (essentially
the new template)
- `hx-trigger="every 5s"`: call every 5 seconds
- `hx-indicator=".divider"`: the `is-loading` class shouldn't be added
to the div during the request, so set it on an element it has no effect
on
- Render "Since Last GC Time" with `<relative-time>`, so we send a
timestamp
