 *
 * This component renders a single chat message including:
 * - Message text (sanitized)
 * - Attachments (if any)
 * - Custom templates for message content and actions (if provided via chat options)
 *
 * It distinguishes sent messages from received messages by comparing
 * the message sender with the current user ID from chat state.
 *
 * The message text is sanitized with DOMPurify before rendering,
 * and can be rendered with a markdown renderer if provided.
