refactor: simplify error handling patterns in e2e config tests

Replace nested match statements with ? operator in run_ansible_configuration()
and run_deployment_validation() functions. This improves code readability and
follows idiomatic Rust error handling patterns.

Changes:
- Simplified nested match/Result patterns to use direct ? operator
- Maintained same error contexts and logging behavior
- Enhanced code maintainability while preserving functionality

Completes Phase 1.3 of e2e-config-tests-cleanup refactor plan.
