feat: add 10 new HTML5 lesson modules (EN + DE)

New lesson modules covering native HTML5 features:
- Details & Summary: disclosure widgets
- Progress & Meter: progress bars and gauges
- Datalist: autocomplete inputs
- Data Attributes: custom data-* attributes
- Dialog: native modal dialogs
- Forms with Fieldset: grouped form controls
- Figure & Figcaption: self-contained content
- Tables: structured data with caption, thead, tbody, tfoot
- Marquee: classic scrolling text (deprecated but fun)
- SVG Basics: drawing circles, rectangles, and lines

Each module includes 2-3 progressive lessons with fancy
styling (pastel gradients, 100vh layouts, etc).
