fix(cli-utilities): read aggregate globalfields.json in readGlobalFieldSchemas (DX-7312)

[harshitha-cstk]

What

readGlobalFieldSchemas() now reads the aggregate global_fields/globalfields.json when present, falling back to per-uid files.

Why

The function ignored the aggregate globalfields.json and only read per-uid files. For aggregate-format exports it returned 0 global fields, which cascaded:

• The audit stripped every global_field reference from content types.
• The import global-fields module created no global fields on the destination.
• Content types / entries then failed with "The referenced Global Field does not exist", and image-preset (and other global-field-nested) entry data was silently dropped.

This is the shared reader used by the audit and the import global-fields/content-types modules, so the single fix corrects all three consumers.

Investigation notes

• Not marketplace extension_uid remapping (that works — verified same-org: apps install, mapper populated, 0 marketplace-extension errors).
• Not version- or node bin/run-vs-csdx-specific: reproduced identically on 2.0.0, 2.0.0-beta.21, 2.0.0-beta.28. The real variable is the export format (aggregate vs per-uid).

Verification

Clean import of the ticket's export into an empty dev11 stack → ✅ IMPORT completed successfully, 0 errors; global fields / content types / entries all imported; extension + marketplace UID mappings applied.
