Fix a broken paragraph in the Dust case study, and the card's screen reader output (#2680)

Three defects found auditing the merged quote work.

The Dust card at "solution of choice" had no blank line before or after it,
so it rendered inside the paragraph. A <figure> implicitly closes a <p>,
which left the following 60 words as a bare text node outside any
paragraph: 16px instead of 18px, tighter leading, and no bottom margin.
This is live on qdrant.tech today. Adding the blank lines restores it; the
file's words are unchanged, only whitespace.

The card also hid the company from screen readers. The logo carried
alt="", and the company name is display:none whenever a logo is present,
so on desktop a screen reader got the name and role and no company at all.
The logo now uses the company as its alt text, which is what it conveys.
The avatar becomes alt="" for the opposite reason - the name sits right
beside it, so repeating it just made the name announce twice.

Also restores the trailing newline on case-study-bayer.md.
