fix: replace raw codes and internal IDs in the console with Chinese labels

Found in v0.2 visual QA (docs/plan/09-visual-qa.md):
- actor strings (admin_session:<uuid>, user:<uuid>, system) -> 管理员/系统/API Key
  in policy revisions, subscriptions, inbox, trash, business tasks, organize detail
- cache volume without key shows the downloader name instead of instance:<uuid>
- download timeline/plan: task and organize statuses, plan purpose, priority and
  status reason localized; audit gets labels for capability/files/site/feed actions
- organize record reason uses conflict detail (没有可入库的主视频) instead of
  blocked:no_main_video; slot/candidate reasons drop inflight:<uuid>
- identity decision summary no longer shows no_viable_candidate
- upstream test: 'Connection error.' classified as network, with a Chinese hint
- new policy draft prefills key default (placeholder looked like a value)
- dialog/sheet close sr-only text in Chinese
