fix(demo): drop VIN input from footer CTA — text + button only

Footer carried a VIN input intended to let demo visitors signup with their
own vehicle pre-filled, but it duplicated the hero's VIN search and added
friction at a moment the visitor is already deciding "should I sign up?"
— not "let me re-type a VIN". Reverted to a clean B2B trust strip + single
"Hesap Aç" primary CTA.

* New DemoFooterCta replaces the prior DemoVinCta. Visitors who want to
  query their own VIN use the hero or the /register page itself.
* Component renamed (file + symbol) so the name reflects what it does;
  the old file is removed. Both /demo and /demo/categories/$id swapped.
* Copy & B2B framing unchanged from the spec ("Sınırsız şase sorgulamak
  için ücretsiz hesap aç" / trust strip).
