🛡️ Sentinel: [CRITICAL] Fix PII leakage in Sentry crash reports

[google-labs-jules]

🚨 Severity: CRITICAL
💡 Vulnerability: The bug reporting UI temporarily injected the user email into the global SentrySDK scope but failed to use a defer block. If the submission network request threw an error, the email was never cleared, leaking PII into subsequent unrelated Sentry crash reports.
🎯 Impact: Sensitive user data (email) could be leaked into external bug reports.
🔧 Fix: Used a defer block to ensure Sentry SDK state is cleared regardless of whether the function succeeds or throws an error.
✅ Verification: Manual code review confirms defer block usage.
