This change downgrades SQLAlchemy from 2.0.23 to a version constraint that excludes 2.x entirely. This appears to be a breaking change that could cause compatibility issues with existing code written for SQLAlchemy 2.x. Consider if this change is intentional and ensure all SQLAlchemy usage in the codebase is compatible with 1.x APIs.

Using Field to provide examples for request body parameters is not the correct approach. The Field function is for Pydantic model fields, not for endpoint parameters. Instead, use the example parameter in the route decorator or define examples in the Pydantic model's Config.schema_extra. This same issue appears in multiple route files.

Using Field for path parameters is incorrect. Path parameters should be simple type annotations. The Field function is for request body fields in Pydantic models, not for path or query parameters in FastAPI endpoints.
