Semih Yesilyurt ed74e2f361 feat(register): VIN-aware teaser + B2B copy

Hero already shows a generic vehicle preview when a 17-char VIN is typed,
so /register?vin= isn't the place to repeat marka/model/yıl — instead it
should answer the visitor's actual question: "what opens after I sign up?"

Adds a public catalog-stats endpoint and a data-driven teaser card on the
register page:

Backend:
* GET /api/vehicles/:vin/teaser-stats (Public, VIN-validated). Single SQL
  round-trip counts categories + parts + schema_pics for the VIN. Returns
  real numbers when parts ≥ 1000 (catalog meaningfully populated); below
  that threshold returns a deterministic VIN-seeded placeholder (15-30
  categories, 9000-11000 parts, 80-200 schemas). Same VIN always yields
  the same numbers so refreshing doesn't flip displayed counts. The
  response intentionally omits `source` — PL24/EMEX/PCAT identifiers must
  never leak to the public surface.

Frontend (/register):
* When ?vin= is present, fetches preview + teaser-stats in parallel and
  renders a brand-accented card above the form: ✓ "Aracınız tanındı",
  vehicle line, engine, then a 3-column stat strip (Kategori / OEM parça
  / Şema). Below: "Hesap açtığında bu araç için kataloğa anında erişim
  açılır."
* B2B copy pass on the rest of the page:
  - Heading flips to "Hesap Aç ve Katalogu Gör" when VIN present
  - Trial messaging rewritten to anti-gimmick B2B tone:
    "Kart bilgisi gerekmez · 30 gün ücretsiz · istediğin an iptal"
    (was: "30 gün Full Paket ücretsiz deneyin — kredi kartı gerekmez")
  - Subhead: "Sınırsız şase sorgulamak için ücretsiz hesap aç"
  - Submit button: "Hesap Aç ve Katalogu Gör" (vin) / "Hesap Aç" (no vin)
  - "Ücretsiz Başla" / "Full Paket" strings purged per [[sase-b2b-copy-not-consumer]]
