Fix CI workflow: update PChatBot references to PeasyAI

- Update path triggers from Src/PChatBot/** to Src/PeasyAI/**
- Update working-directory from Src/PChatBot to Src/PeasyAI
- Update workflow name to PeasyAI Contract Tests

The directory was renamed but the workflow still referenced the old name,
so CI would never trigger and would fail if run manually.
