[Maintainence]Added security test

[sumukhswamy]

Description

This Cypress test verifies that an internal user with the reports_full_access role can be created, assigned the correct permissions, and mapped to the role in a security-enabled OpenSearch Dashboards environment. The test is especially relevant due to a regression introduced in OpenSearch 2.19, where a refactor of the PrivilegesEvaluator class in the security plugin removed the logic for setting or reading the requestTenantAccess field. This field is critical for the reporting plugin to determine which tenants a user can access. Without it, the reporting plugin receives a null value and denies access to reporting features, even for users who should have permission. This test helps ensure that user and role setup works as expected and highlights the impact of the missing requestTenantAccess logic on reporting access.
