**Original Pull Request Body**

To make sure any overrides are applied to the user even when searched by 
UPN or email address sysdb_search_user_by_upn_with_view_res() is now used
in the cache request code.

Code Review

This pull request backports changes to improve user lookups by UPN or email address when using ID views. It introduces a new function sysdb_search_user_by_upn_with_view_res and updates the cache_req plugin to use it, ensuring that user overrides are correctly applied. The old sysdb_getpwupn function is removed. My review has identified a critical logical issue in the new function that could lead to lookup failures, and an unresolved merge conflict in one of the test files that needs to be addressed.
