Potential fix for code scanning alert no. 59: Clear-text logging of sensitive information (#12069)

Potential fix for
[https://github.com/infiniflow/ragflow/security/code-scanning/59](https://github.com/infiniflow/ragflow/security/code-scanning/59)

General approach: ensure that HTTP logs never contain raw secrets even
if they appear in URLs or in highly sensitive endpoints. There are two
complementary strategies: (1) for clearly sensitive endpoints (e.g.,
OAuth token URLs), completely suppress URL logging; and (2) ensure that
any URL that is logged is strongly redacted for any parameter name that
might carry a secret, and in a way that static analysis can see is a
dedicated sanitization step.

Best targeted fix here, without changing behavior for non-sensitive
traffic, is:

1. Strengthen the `_SENSITIVE_QUERY_KEYS` set to include any likely
secret-bearing keys (e.g., `client_id` can still be sensitive, depending
on threat model, so we can err on the safe side and redact it as well).
2. Ensure `_is_sensitive_url` (in `common/http_client.py`, though its
body is not shown) treats OAuth-related URLs like those from
`settings.GITHUB_OAUTH` and `settings.FEISHU_OAUTH` as sensitive and
thus disables URL logging. Since we are not shown its body, the safe,
non-invasive change we can make in the displayed snippet is to route all
logging through the existing redaction function, and to default to *not
logging the URL* when we cannot guarantee it is safe.
3. To satisfy CodeQL for this specific sink, we can simplify the logging
message so that, in retry/failure paths, we no longer include the URL at
all; instead we log only the method and a generic placeholder (e.g.,
`"async_request attempt ... failed; retrying..."`). This fully removes
the tainted URL from the sink and addresses all alert variants for that
logging statement, while preserving useful operational information
(method, attempt index, delay).

Concretely, in `common/http_client.py`, inside `async_request`:

- Keep the successful-request debug log as-is (it already uses
`_redact_sensitive_url_params` and `_is_sensitive_url` and is likely
safe and useful).
- In the `except httpx.RequestError` block:
- For the “exhausted retries” warning, remove the URL from the message
or, if we still want a hint, log only a redacted/sanitized label that
doesn’t derive from `url`. The simplest is to omit the URL entirely.
- For the per-attempt failure warning (line 162), similarly remove
`log_url` (and thus any use of `url`) from the formatted message so that
the sink no longer contains tainted data.

These changes are entirely within the provided snippet, don’t require
new imports, don’t change functional behavior of HTTP requests or retry
logic, and eliminate the direct flow from `url` to the logging sink that
CodeQL is complaining about.
