feat(orchestrator): prune steps for focused validation runs

[abegnoche]

Summary

• Pre-resolve explicit pytest -k / -m selection against configured validation entries so focused runs skip unrelated provider steps.
• Keep selected validation step dependencies plus lifecycle helper steps declared with requires_available_validations.
• Preserve excluded validations in orchestration/JUnit output as test_excluded instead of reporting them as missing steps.

Test plan

• uv run ruff check isvctl/src/isvctl/orchestrator/loop.py isvctl/tests/test_orchestrator_loop.py isvctl/tests/providers/nico/test_nico_provider.py
• uv run pytest isvctl/tests/test_orchestrator_loop.py isvctl/tests/providers/nico/test_nico_provider.py -q
