feat(providers): route only the generate submit through the proxy

Browse Source 
Extends the adobe split to leonardo, krea, imagine, runway (image+video) and chatgpt: reference-image upload, polling and result download egress on the local IP; only the generate/task-create submit uses proxy.url. chatgpt keeps its anti-bot-guarded submit+upload phase on the proxy and moves only the existing second (poll/resolve/download) session to local. custom is already direct. Build+vet pass; adobe verified live, the other providers are code-complete but not yet live-tested (no dev accounts).
