fix(downloads): humanized reasons and TechInfo on the download panel (DL-2b)

- board organize hint uses DEAI-2 reasonLine; add transfer_failed, blocked,
  blocked_by_conflict, main_failed, not_imported_kind, target_root_not_managed,
  download_removed to the reason table with tests
- download detail / plans tab: internal ids, raw codes and JSON moved into TechInfo
- library versions tech block switched to TechInfo (TODO(DEAI-2))
- copy: glossary terms (no 接管/候选), plan reason codes no longer shown raw
