[ui] Handle jobs pagination

[philrenaud]

Handle pagination of the endpoint(s) provided from #19339

Phase 1:

• Establish a blocking query watcher with per_page that updates whenever jobs within that range have updated
• Observe changes to the N+1th job (where N is per_page) that updates the next_token parameter and, to the user, makes the "next" button clickable
• Establish prev/next buttons
• Establish "prev" functionality when the user has refreshed the page at an already-paginated point (Note: this is tricky because there is no concept of a prev_token, and reverse=true doesn't appear to work on the jobs endpoint)
• Set up searching and filtering options #20425
• Handle parent jobs' children status #20491
• Now that the endpoint doesn't return child jobs, have a parent job loaded directly look them up for child job table purposes

Phase 2:

• Port aggregateAllocStatus as a filterable/queryable parameter for our endpoint
