    In an automated assessment system, design a function that takes a student's submission ID and generates the next valid palindromic ID number greater than the input ID. The generated palindromic ID must be the smallest possible number larger than the input that reads the same forwards and backwards, ensuring efficient two-way verification in the database system.
