.SYNOPSIS
    Shared setup helper for integration tests.
    Dot-source this in each integration test file's BeforeAll block.

.DESCRIPTION
    Provides:
    - Module loading via _TestHelper.ps1
    - Environment variable reading (PVETEST_*)
    - Skip helper functions
    - Connect-TestPve: establishes a credential-based connection if needed
    - Resource discovery helpers for cross-file test dependencies
