chore: remove the sponsor material for Doubao and Atlas Cloud

The about pages lose the "Sponsored by ByteDance Doubao" card, the
promotional links in the provider list and the thanks paragraph; the
"bring your own key" note stays. The quota toast no longer shows the
Volcengine sign-up paragraph, and its messages in the four languages no
longer mention a sponsor. The provider guides lose the "free tokens"
promo line. The logo and invite images used only by that material are
deleted. Doubao and Atlas Cloud remain supported providers.
