Show the Browser API's error body instead of a bare HTTP status

[jehrr]

The canary's endpoint step failed with only 404 Client Error: Not Found for url: https://api.2captcha.com/browser/connection. _call ran raise_for_status(), which drops the response body — and the body is where the Browser API names the cause (ERROR_ACCOUNT_NOT_FOUND, ERROR_CUSTOM_PROXY_AUTH, …).

Now an HTTP error prints HTTP <status>: <body> with the body passed through the existing safe() masker and redact(), so key, password and login fields stay masked; a non-JSON body is reported by size only.

Checked offline with a stubbed requests: a 404 JSON body shows its errorCode with key/password masked; a non-JSON body prints only its length; a 200 still returns the data. smoke_test.py 684/0, pytest 94 passed, ci_checks.py --all clean (core-only venv).
