feat: server-side pagination and filtering for admin queues page

- Move queue, status, and offset to URL search params (?queue=&status=&offset=)
- Load jobs server-side in +page.server.ts with auth token (matches other admin pages)
- Derive total from adminQueues counts (waiting+active+completed+failed+delayed)
  so pagination knows total without an extra query
- Add fetchFn/token params to getAdminQueueJobs for server-side use
- Retry/remove/pause/resume actions now use invalidateAll() instead of local state
