feat(articles): rewrite B2B article CTAs — directory → /quote form

All 12 hall-building articles now link to /quote (leads.quote_request).
Previously: 2 had broken directory prose, 4 had unlinked planner mentions,
4 had broken [→ placeholder] links, 2 had scenario cards but no CTA link.

- Group 1 (bauen/build-guide): replace directory section with quote CTA
- Group 2 (kosten/risiken): link planner refs, append quote CTA
- Group 3 (finanzierung): append quote CTA after scenario card
- Group 4 (standort/businessplan): fix broken [→] links to /de|en/planner,
  append quote CTA

CTA copy is contextual per article. Light-blue banner pattern, .btn class.
B2C gear articles unaffected.

 ## [Unreleased]
 
+### Fixed
+- **B2B article CTAs rewritten — all 12 now link to `/quote`** — zero articles previously linked to the quote lead-capture form. Each article's final section has been updated:
+  - `padel-halle-bauen-de` / `padel-hall-build-guide-en`: replaced broken "directory" section (no link) with a contextual light-blue quote CTA block
+  - `padel-halle-kosten-de` / `padel-hall-cost-guide-en`: planner mention linked to `/de/planner` / `/en/planner`; quote CTA block appended
+  - `padel-halle-risiken-de` / `padel-hall-investment-risks-en`: planner sensitivity-tab mention linked; quote CTA block appended
+  - `padel-halle-finanzierung-de` / `padel-hall-financing-germany-en`: quote CTA block appended after scenario card embed
+  - `padel-standort-analyse-de` / `padel-hall-location-guide-en`: fixed broken `[→ Standortanalyse starten]` / `[→ Run a location analysis]` placeholders (no href) to `/de/planner` / `/en/planner`; quote CTA block appended
+  - `padel-business-plan-bank-de` / `padel-business-plan-bank-requirements-en`: fixed broken `[→ Businessplan erstellen]` / `[→ Generate your business plan]` placeholders to `/de/planner` / `/en/planner`; quote CTA block appended
+  - CTA copy is contextual per article (not identical boilerplate); uses the light-blue banner pattern (`.btn` class, `#EFF6FF` background) consistent with other generated articles
+
+
+- **Article editor preview now renders HTML correctly** — replaced the raw `{{ body_html }}` div (which Jinja2 auto-escaped to literal `<h1>...</h1>` text) with a sandboxed `<iframe srcdoc="...">` pattern. The route builds a full `preview_doc` HTML document embedding the public site stylesheet (`/static/css/output.css`) and wraps content in `<div class="article-body">`, so the preview is pixel-perfect against the live article. The `article_preview` POST endpoint uses the same pattern for HTMX live updates. Removed ~65 lines of redundant `.preview-body` custom CSS from the editor template.
+
 ### Changed
 - **Semantic compression pass** — applied Casey Muratori's compression workflow (write concrete → observe patterns → compress genuine repetitions) across all three packages. Net result: ~200 lines removed, codebase simpler.
   - **`count_where()` helper** (`web/core.py`): compresses the `fetch_one("SELECT COUNT(*) ...") + null-check` pattern. Applied across 30+ call sites in admin, suppliers, directory, dashboard, public, and planner routes. Dashboard stats function shrinks from 75 to 25 lines.
