fix(models): Update ValidatedIntEnum class to properly serialize with…

[heliocastro]

… strings

[Copilot]

Pull request overview

This PR updates the ValidatedIntEnum Pydantic integration so enums serialize as their string names (and expose a string-enum JSON schema), adds focused tests for the new behavior, and bumps project / tooling versions accordingly.

Changes:

• Update ValidatedIntEnum core schema to serialize enums as name and emit a string enum JSON schema.
• Add new tests and repo-config fixtures to validate enum behavior and YAML config validation (including known-invalid fixtures).
• Bump python-ort version to 0.8.5 and update ty dependency to >=0.0.23; adjust SPDX header contact details in tests.
