test(i18n,sub): clear the three standing vitest reds (item 10)

- i18n dead keys: drop 13 keys with no reference left (pages.xray.routeTester*
  from the P9 feature removal, tgbot.online superseded by tgbot.messages.online,
  tgbot.commands.restartSuccess/restartFailed from the rewritten restart handler)
- i18n key sets: add the P9 forwarding block (20 keys) to the 11 locales that
  missed it, as English placeholders per repo convention; all 13 locales now
  carry identical key sets
- subscription port test: the case predated P7 — clearing the port field is the
  explicit subPort 0 (no port in generated links) opt-in via onNumber onClear,
  so assert updateSetting is called with { subPort: 0 } instead of never called

No component code, UI behavior, or styles touched.
