🛡️ Sentinel: [MEDIUM] Fix Authorization header leakage on redirect

[adolago]

🚨 Severity: MEDIUM
💡 Vulnerability: The UriModule manually added the Authorization header to requests. reqwest forwards manually set headers to redirected URLs, potentially leaking credentials to third-party domains if a redirect occurs.
🎯 Impact: An attacker could potentially harvest credentials by redirecting a legitimate request to an attacker-controlled server.
🔧 Fix: Updated UriModule to use reqwest::RequestBuilder::basic_auth() and bearer_auth(), which implement secure header handling on redirects.
✅ Verification: Ran existing tests to ensure no regression. Manual verification of logic confirms alignment with reqwest security documentation.
