kw_only on frozen mock types; freeze key validator routes

[adamtheturtle]

Summary

• CloudDatabase, VuMarkDatabase, ImageTarget, VuMarkTarget: add kw_only=True.
• RequestData, Route (_mock_common): add kw_only=True.
• key_validators._Route: frozen=True, kw_only=True.
• Test helpers Endpoint, VuMarkCloudDatabase, InactiveVuMarkCloudDatabase: kw_only=True.

Existing call sites use keyword arguments.

Testing

uv run pytest tests/mock_vws/test_target_validators.py — passed. Full suite hits Docker/real-Vuforia parametrization in this environment.

Note

Medium Risk
This is a potentially breaking API change: several public/semipublic dataclasses now require keyword-only construction, which will fail at runtime for any downstream positional call sites. Behavior is otherwise unchanged and existing in-repo call sites already use keywords.

Overview
Makes multiple mock model/helper dataclasses keyword-only by adding kw_only=True to RequestData, Route, CloudDatabase, VuMarkDatabase, ImageTarget, VuMarkTarget, and key test helpers (e.g. Endpoint, VuMarkCloudDatabase).

Tightens immutability/consistency in key validation by making key_validators._Route a frozen=True keyword-only dataclass, preventing accidental mutation of route definitions during validation.
