Create safeGetBySysId utility for safe record retrieval

This utility function simplifies fetching a GlideRecord by sys_id with built-in null checks and clear logging. It prevents repeated boilerplate code and ensures that missing records are clearly logged in sys.log. Includes an example usage for fetching an incident.

+
+> Safely fetch a GlideRecord by `sys_id` and log clearly if not found.
+
+**Use case:**  
+I often need to fetch a single record inside background scripts or Script Includes and don’t want to keep repeating the same `gr.get()` + null checks. This helper makes it a one-liner and keeps logs human-readable.
+
+```javascript
+/**
+ * safeGetBySysId(table, sysId)
+ * Returns GlideRecord object or null if not found.
+ */
+function safeGetBySysId(table, sysId) {
+  if (!table || !sysId) {
+    gs.warn('safeGetBySysId: Missing parameters.');
+    return null;
+  }
+
+  var gr = new GlideRecord(table);
+  if (gr.get(sysId)) {
+    return gr;
+  }
+
+  gs.warn('safeGetBySysId: No record found in ' + table + ' for sys_id ' + sysId);
+  return null;
+}
+
+// Example:
+var inc = safeGetBySysId('incident', '46d12b8a97a83110eaa3bcb51cbb356e');
+if (inc) gs.info('Found incident: ' + inc.number);
