Adds support for scraping recipes from thomas-kocht.de.

Closes #1477

Site structure

Thomas Kocht uses Avada/Fusion page builder (WordPress). Recipe schema.org only includes name, description, image, and aggregate rating — ingredients, instructions, time and yields require HTML parsing:

• Title / Description / Image / Ratings: from JSON-LD schema.org/Recipe
• Ingredients: <h3>Zutaten …> heading followed by a <ul><li> list
• Instructions: <div class="fusion-title"> divs containing <h2>Schritt N</h2>, each followed by a <div class="fusion-text"> with <h4> sub-title and <p> paragraphs
• Total time: parsed from a <p>Vorbereitungszeit: X Minuten | Kochzeit: Y Minuten | …</p> paragraph
• Yields: parsed from the same info paragraph (Ergibt N Stück)
• Author: hardcoded "Thomas Kocht"

Testing

Tested against the Pfannkuchen recipe from the issue.

All tests pass.
