fix(i18n): correct stale help texts, inverted ko tag logic and placeholder contracts

- viewLocalTooltip: all 9 locales said 'coming soon'; describe the actual
  action (show local versions on main page)
- settings.downloadSkipBaseModels.help / hideEarlyAccessUpdates.help /
  aiProvider.apiBaseHelp: retranslate all locales to the current en wording
  (previous translations described an older source string)
- ko header.filter.tagLogicAny: 'all tags match' was inverted and identical
  to tagLogicAll; fix zh-TW typo 票籤 -> 標籤
- modals.checkUpdates.title/message: restore {typePlural} in zh-CN/zh-TW/ja/ko
- zh-CN recipes.controls.import.downloadLocationPreview: drop invented {path}
  (caller passes no params; it rendered literally)
- zh-TW toast.controls.refreshFailed: restore {action} placeholder
- toast.settings.mappingsUpdated: drop English-inflection {plural} where '<noun>s'
  would corrupt the noun (zh-CN/zh-TW/ja/ko/de/ru/he); caller passes hardcoded 's'
