Fix structured data, OG image dimensions, breadcrumbs, Arabic grammar and footer labels in opposition motions articles

[Copilot]

Review thread #3874605811 flagged 5 categories of defects across the 14 2026-03-02-opposition-motions-*.html files introduced in PR #719.

Changes

All 14 files — OG/JSON-LD image dimensions

• og:image:width/height: 1200×630 → 140×140
• JSON-LD ImageObject width/height: same correction
• Asset is cia-icon-140.webp; declaring 1200×630 caused incorrect social previews

en.html — JSON-LD articleBody removed

• Field contained HTML-escaped, mid-sentence–truncated content; removed entirely per reviewer suggestion

13 non-EN files — Breadcrumb item URLs localized

// Before (all localized pages pointed to non-localized root)
{ "position": 1, "item": "https://riksdagsmonitor.com/" }
{ "position": 2, "item": "https://riksdagsmonitor.com/news/index.html" }

// After (e.g. nl.html)
{ "position": 1, "item": "https://riksdagsmonitor.com/index_nl.html" }
{ "position": 2, "item": "https://riksdagsmonitor.com/news/index_nl.html" }

ar.html — Arabic numeral agreement

• قدم نواب المعارضة 20 اقتراحات جديدة → قدّم نواب المعارضة 20 اقتراحاً جديداً

13 non-EN files — Footer "Quick Links" labels localized

• Home/News replaced with language-native equivalents (Accueil/Actualités, Hjem/Nyheder, Startseite/Nachrichten, Inicio/Noticias, Etusivu/Uutiset, דף הבית/חדשות, ホーム/ニュース, 홈/뉴스, Startpagina/Nieuws, Hjem/Nyheter, Hem/Nyheter, 首页/新闻)
• en.html footer unchanged (English labels are correct)
