feat(web-shell): add Russian locale for the Goal card and Goals dialog

The web-shell i18n shipped only en and zh-CN and collapsed every other
browser locale (e.g. ru-RU) to en in normalizeLanguage, so a Russian
user saw the Goal card and the Goals dialog in English around a
Russian objective.

Add a partial ru catalog for the goal.*/goals.* keys with Russian
pluralisation (ход/хода/ходов, токен/токена/токенов,
активная цель/активные цели/активных целей). getTranslator already
falls back per key to EN (messages[key] ?? EN[key] ?? key), and the
partial catalog relies on that for every other key — the behaviour this
locale has been running with as an installer patch.

- WEB_SHELL_LANGUAGES / LANGUAGE_LABELS: add 'ru' / 'Русский [ru]' to
  the settings picker
- normalizeLanguage: accept ru / ru-ru / russian / русский
- languageSettingToWebShellLanguage: accept the same spellings for the
  daemon's general.language setting
- WebShellProps.language / WebShellTranscriptProps.language: accept the
  'ru' and 'ru-ru' raw values
- surfaces with their own WebShellLanguage-keyed copy tables
  (StandaloneAuth, RootErrorFallback, conversation search, desktop
  relay) reuse the EN copy for ru, same partial-catalog policy
- re-measure the transcript entry size budget for the catalog
  (+4,649 to 1,325,015; ceiling raised to 1,328,000)
