Auto-generate OpenAPI examples from Pydantic models

[usmanimamu17-create]

Problem

docs/API.md is hand-curated and drifts; OpenAPI examples are empty {}.

Why

Auto-generated examples stay in sync with reality for the lifetime of the API.

Outcome

Every Pydantic model has json_schema_extra={"example": ...}. Test enforces completeness.

Acceptance

• /openapi.json includes example everywhere
• Test enforces
• docs/API.md regenerable

Files

• app/models/outage_dto.py
• app/models/payment.py
• tests/test_openapi_examples.py (NEW)
