Function traverseAndUpdatePrecisionValues

Recursively traverses and updates all PrecisionValue fields in an object If providedScope is not specified, it will be detected from the data:

• Uses 'scope' or 'mainScope' fields at the root level
• For elements in arrays with their own 'scope' field, uses that element's scope

This function is particularly useful for converting DUC data between different measurement scopes, such as when elements need to be converted from their original scope to a target scope (e.g., 'mm' to 'in').

When processing arrays of elements (e.g., an 'elements' array), each element will be processed using its individual scope if available, falling back to the provided or detected scope.
