/**
 * @description:
 * This function sanitizes field names to ensure they are valid for form validation and avoid issues with nested object notation.
 * - Replaces dots ('.') with underscores ('_') because dot notation is used to access object properties in many form validation libraries (e.g., useForm),
 *   and having dots can cause the field to be treated as a nested object rather than a simple property.
 * - Replaces square brackets ('[]') with underscores ('_') to avoid the field being interpreted as an array or nested structure.
 *
 * This ensures the field names are flat, unique, and compatible with form validation libraries.
 * If the sanitized name already exists, a counter is appended to make it unique.
