peter fa35925cc6 fix(downloads): shell-safe names, refresh display_name on re-download, GC orphan sweep
Follow-up to user prod testing of 0.51.0:
- re-download now clears job.display_name so the card title + Content-Disposition filename are
  re-derived from the freshly-cleaned title (previously an auto-name from an older un-cleaned
  title — still carrying a "… views · … reactions |" prefix — survived the rebuild).
- on-disk AND served names are now a strict shell-safe slug: only [A-Za-z0-9._-] survive; every
  other char (the "!" the user saw, plus ( ) [ ] & $ ' " ; | ? * …) collapses to "_". The id no
  longer uses [brackets] (glob metacharacters). Shared _slug helper for sanitize + display_filename.
- GC gains a 5th pass: sweep on-disk files/dirs no ready asset owns (old accented channel dirs, a
  poster from a superseded naming scheme left after a re-download), skipping the dot system trees
  and anything newer than an hour so an in-flight download is never touched.
- Tests: slug strips !/$/()[]; rel_path is bracket-free; orphan-sweep keeps owned/system/fresh files.
