The TestJWTAuthenticationFlow was failing because the IAM policies for
S3ReadOnlyRole and S3AdminRole were missing the 'sts:ValidateSession' action.
### Problem:
- JWT authentication was working correctly (tokens parsed successfully)
- But IsActionAllowed returned false for sts:ValidateSession action
- This caused all JWT auth tests to fail with errCode=1
### Solution:
- Added sts:ValidateSession action to S3ReadOnlyPolicy
- Added sts:ValidateSession action to S3AdminPolicy
- Both policies now include the required STS session validation permission
### Test Results:
✅ TestJWTAuthenticationFlow now passes 100% (6/6 test cases)
✅ Read-Only JWT Authentication: All operations work correctly
✅ Admin JWT Authentication: All operations work correctly
✅ JWT token parsing and validation: Fully functional
This ensures consistent policy definitions across all S3 API JWT tests,
matching the policies used in s3_end_to_end_test.go.
