NethLink: does not accept uppercase in username

[viktec]

Description

When authenticating to NethLink, credentials work only if the username is entirely lowercase.
A user created in the account database with uppercase letters (e.g. AlfaTest2) cannot log in to NethLink, while the same account works correctly in CTI and other services.

This behavior is inconsistent with other Nethesis products (e.g. user portal) and may confuse end users.

---

Steps to reproduce

1. Create a user in the account database with uppercase letters (e.g. AlfaTest2).

2. Try to log in to NethLink with that username.

3. Repeat login using the same username in all lowercase (alfatest2).

---

Expected behavior

Login should work regardless of uppercase/lowercase in the username.

---

Actual behavior
Login fails if the username contains uppercase letters.

Components
