fix(css): constrain legal pages (impressum, datenschutz) to main container width

The .legal-page <main> element had no CSS rules at all, so the
Impressum and Datenschutz text was rendering flush against the left
edge of the viewport (x=0, width=1265 at 1280px viewport). Both
view files share the .legal-page class, so a single CSS rule fixes
both.

Added a complete legal-page stylesheet (max-width 1200px, margin
auto, 6rem 3rem padding, matching .floors-section / .lage-section /
.pricing-section / .contact-section), plus minimal typography for
h1/h2/h3, body text, lists, links, the .legal-divider <hr>, the
.legal-back link, and a 768px mobile padding adjustment.

Measured on 1265px viewport:
- main.legal-page: 32.5/1200 (was 0/1265)
- h1 content area: 80.5/1104 inside the 3rem horizontal padding
