Drop question-report entirely, obfuscate the mailto link instead

The report button logged to an event stream nothing ever read - no
notification, no dashboard, just a durable no-op. A browser back
button already covers "this page wasn't helpful" better than a button
that silently does nothing visible to anyone but the visitor who
clicked it.

The mailto address is now assembled from data-user/data-domain on a
real mouse event instead of baked into the server-rendered href -
keeps a plain mailto: string (what bulk scrapers regex HTML for) out
of what a generic bot crawl sees, without hiding the contact option
from an actual visitor.
