fix(web): use shared PageTopbar on /gitlab so the page has a header (#1062)

The GitLab page rendered a custom in-file header instead of the shared
PageTopbar used by /github, /jira, and /linear — leaving /gitlab without
the standard breadcrumb / home navigation. Swap it for PageTopbar with
the GitLab brand icon and host subtitle, and move the Refresh button
into the topbar's actions slot.
