style(copy): punctuation rules and site-wide fix with a CI check (QA U11)

- glossary: 10 punctuation rules (full-width in Chinese, CJK/Latin spacing,
  full-width parens around Chinese, single ellipsis, 「」 quotes, period rules)
- scripts/check-copy-punctuation.mjs: checks string literals, templates and JSX
  text (not comments, types, keys, match/compare strings); --fix, --strict,
  --by-file; wired into deno task ci as check:copy in warn mode
- --fix applied to web, server and contracts; files other lanes were editing
  (subscriptions, sites, browser, agent, auth/account, inventory) left for them
- tests updated for the changed messages
