Township UI: regen/train progress survives a page reload

Tag regen/train jobs with kind/name/jtype and add a /active-jobs endpoint listing
running ones. On Characters/Environments page load, resumeActiveJobs() re-attaches
the live progress display to any in-flight job for the matching card, so a reload
(or reopening the tab) keeps showing progress until completion.
