Patrik 8f85da8931 fix(plugin-import-export): json preview and downloads preserve nesting and exclude disabled fields (#13210 )

### What?

Improves both the JSON preview and export functionality in the
import-export plugin:
- Preserves proper nesting of object and array fields (e.g., groups,
tabs, arrays)
- Excludes any fields explicitly marked as `disabled` via
`custom.plugin-import-export`
- Ensures downloaded files use proper JSON formatting when `format` is
`json` (no CSV-style flattening)

### Why?

Previously:
- The JSON preview flattened all fields to a single level and included
disabled fields.
- Exported files with `format: json` were still CSV-style data encoded
as `.json`, rather than real JSON.

### How?

- Refactored `/preview-data` JSON handling to preserve original document
shape.
- Applied `removeDisabledFields` to clean nested fields using
dot-notation paths.
- Updated `createExport` to skip `flattenObject` for JSON formats, using
a nested JSON filter instead.
- Fixed streaming and buffered export paths to output valid JSON arrays
when `format` is `json`.
