CVE-2026-32609: Glances has Incomplete Secrets Redaction: /api/v4/args Endpoint Leaks Password Hash and SNMP Credentials

The GHSA-gh4x fix (commit 5d3de60) addressed unauthenticated configuration secrets exposure on the /api/v4/config endpoints by introducing as_dict_secure() redaction. However, the /api/v4/args and /api/v4/args/{item} endpoints were not addressed by this fix. These endpoints return the complete command-line arguments namespace via vars(self.args), which includes the password hash (salt + pbkdf2_hmac), SNMP community strings, SNMP authentication keys, and the configuration file path. When Glances runs without --password (the default), these endpoints are accessible without any authentication.
