Miggo AIRoot Cause Analysis

The vulnerability stems from the GetManifests function in application.go returning unredacted Secret manifests. The patch adds a loop that specifically processes Secret manifests using diff.HideSecretData before returning them. The test/e2e/app_management_test.go changes verify that secrets are now redacted in GetManifests responses. Prior to the fix, this function lacked the critical secret redaction logic, making it the clear entry point for sensitive data exposure.
