🔒 Sentinel: [HIGH] Fix SQL Injection in DesignationController

[ManupaKDU]

🎯 What: Fixed JPQL injection vulnerabilities in DesignationController.java within the getSelectedItems and completeDesignation methods.
⚠️ Risk: User-controlled input (getSelectText() and qry) was directly concatenated into JPQL query strings, which could allow malicious users to execute arbitrary JPQL queries, potentially exposing or modifying sensitive HR designation data.
🛡️ Solution: Replaced string concatenation with safe, parameterized JPQL queries using a Map<String, Object>. The case-insensitive search logic was preserved by utilizing the JPQL upper() function alongside parameterization. Also added the necessary java.util.Map and java.util.HashMap imports.
