  /*
   * Tab Navigation Handler for Digital Signature Certificate Classes
   *
   * Purpose: Manages the active state of tab buttons in the Certificate Classes
   *          section (Class 1, Class 2, Class 3, Our Products).
   *
   * Behavior:
   *   - Listens for click events on all tab navigation buttons (.nav-link)
   *   - When a tab is clicked:
   *     1. Removes the 'active' class from ALL tabs (resets their state)
   *     2. Adds the 'active' class ONLY to the clicked tab
   *
   * Note: Bootstrap 5 handles the actual tab content switching via
   *       data-bs-toggle="tab". This script solely manages the visual
   *       active state styling of the tab buttons to ensure proper
   *       highlighting and user feedback.
   *
   * Dependencies: Requires Bootstrap 5 JS for tab content toggling
