Animate test and device data model diagrams

Two new animated tree diagrams make the test and device data models easy to read at a glance, with example values and pass/fail states streaming in as each entity is highlighted.

• Added an animated tree on the Test Data Model page (Procedure, Run, Phase, Measurement, Validator, Log, Attachment) with live example values and a PASS validator outcome
• Added an animated tree on the Device Data Model page (Part, Revision, Unit, Sub-unit, Batch) with the Batch drawn as a dashed connector to signal that batches are optional and cross-cutting
• Renamed the underlying pages to Test Data Model and Device Data Model and updated every link across the docs
