T4.2: Extract jobs_view.go (list + details + toolbar)

Move the jobs list, details panel, folder filter, toolbar buttons, and
all related helpers out of mainwindow.go into the new jobs_view.go.
newMainView now calls newJobsView(w, svc) which returns a panel and a
refresh closure; the subscriber and history wiring remain in mainwindow.go.

showJobDialog lives in jobs_view.go as a temporary home until T4.3
extracts it to job_dialog.go.
