curl_cffi sets a User-Agent consistent with its JA3 TLS fingerprint.
BaseProvider's custom UA (Chrome/121) conflicted with the chrome120
TLS fingerprint, causing Cloudflare to flag the request as a bot.
Removing the UA from session headers lets curl_cffi manage its own.

chatgpt.com uses Cloudflare's TLS fingerprinting (JA3/JA4) which
blocks Python requests regardless of cookies. curl_cffi impersonates
Chrome's exact TLS handshake, making requests indistinguishable from
a real browser at the transport layer.

Using self._session.cookies.set() ensures the cookie is sent correctly
by the requests session on all calls, including /api/auth/session.
Also add sec-fetch-* headers required by chatgpt.com.

The __Secure-next-auth.session-token cannot be used directly as a Bearer
token. It must first be exchanged via GET /api/auth/session (with the token
sent as a Cookie) to obtain a short-lived accessToken. This accessToken is
then used as the Authorization: Bearer header for all backend-api calls.
