/**

/**
 * Sanitizes FileMaker OData JSON responses by replacing unquoted `?` values with `null`.
 *
 * FileMaker uses `?` to represent undefined/null values in its OData responses,
 * but this is not valid JSON. This function converts those to proper `null` values.
 *
 * The regex uses two patterns:
 * 1. `/:\s*\?(?=\s*[,}\]])/g` - for values in objects (after `:`)
 * 2. `/(?<=[\[,])\s*\?(?=\s*[,\]])/g` - for values in arrays (after `[` or `,`)
 *
 * @param text - The raw response text from FileMaker OData API
 * @returns Sanitized JSON string with `?` values replaced by `null`
 *
 * @example
 * sanitizeFileMakerJson('{"field1": "valid", "field2": ?, "field3": null}')
 * // Returns: '{"field1": "valid", "field2": null, "field3": null}'
