feat(web): align pricing cards with subscription page

Bring the public pricing cards in line with the in-app subscription page and
strengthen the CTA:
- Move the "Popüler" badge from 2 Marka to Full Paket (one consistent story
  across both surfaces).
- CTA "Başla" -> "Ücretsiz Başla" (leans on the free trial the flow grants).
- Yearly line now uses a consistent ₺ format ("veya ₺2.000,00/yıl") plus a
  "· 2 ay bedava" savings cue instead of the bare, differently-formatted
  "veya 2.000,00 TL/yıl".
- Plan-decision helper above the grid ("Hangi planı seçmeliyim? …").
