feat(provider): support per-source proxy_url for geo-blocked upstreams

Upstreams like justwoker/tabitoken sit behind Cloudflare geo/IP blocks and
only respond through a proxy. A global env proxy is wrong (intranet sources
trae/localzen must stay direct), so add an explicit per-source proxy_url
that overrides http.ProxyFromEnvironment for just that source. Sources
without proxy_url keep the existing env/direct behavior.

Also accepts a User-Agent header per source (config already supported
headers) so CF-fronted resellers can be reached.

Verified e2e: tabitoken and justwoker now return tool_calls through
127.0.0.1:7890 (clash); trae stays direct. Full go test -tags luajit
passes.
