tests: Add mock tests for HTS221 auto-trigger after poweroff.

[nedseb]

Summary

Closes #95.

• Add 3 mock tests exercising the _ensure_data() / trigger_one_shot() auto-trigger path:
  • Auto-trigger temperature after poweroff — calls poweroff() then temperature()
  • Auto-trigger humidity after poweroff — calls poweroff() then humidity()
  • Auto-trigger read after one-shot mode — calls trigger_one_shot() then read()
• Add setup support in executor.py run_action() — allows calling methods on the driver instance before the main test action

Test plan

python3 -m pytest tests/ -k "hts221 and mock" -v

Pull request overview

This PR adds mock tests for the HTS221 driver's auto-trigger path (_ensure_data() / trigger_one_shot()), which was previously untested in mock mode. It also introduces a setup mechanism in the test executor to call driver methods before the main test action.

Changes:

• Added 3 new mock-only YAML test scenarios exercising the auto-trigger path after poweroff() and trigger_one_shot()
• Added setup step support in executor.py's run_action() to call preparatory methods before the main action
