i18n(ja): fit labels found in the screenshot review

- Shorter layer and segment labels that wrapped or broke mid-word in the
  narrow panels: ALPRカメラ, 宇宙ミッション 30日, 地図と比較, 対象.
- Window readouts put the value after the label (空/海ウィンドウ 250 km),
  so a unit never runs into Japanese text.
- 情勢図 for the GhostMaps intel picture; Googleストリートビュー joined like
  any Latin product name in the guide.

 - No space between Japanese and Latin letters, digits or a `{placeholder}`: 「AIS船舶」, 「Spaceを長押しで話す」, 「{count}件」, 「{name}を表示」.
 - Two exceptions keep the space: a Japanese label before its value in a readout (「雲量 {pct}%」, 「ステーション {id}」, 「高度 {altitude}」), and the state words in toggles (「CCTV オン」, 「ラジオ オフ」).
 - Loanwords are katakana with the long-vowel mark, as in Microsoft and Apple style: ユーザー, ブラウザー, ビューアー, プロバイダー, レイヤー, フィルター, モニター, パラメーター. Pick one katakana form per term and keep it (see the glossary).

Google's own product names use Google's Japanese: Google ストリートビュー. Nepal place names in the Bhote Koshi scenes stay in Latin script, as in zh-CN; country and well-known city names are translated (ネパール, 東京, オースティン).
