fix: code scanning alert no. 175: Log Injection

[yacosta738]

Fixes https://github.com/dallay/lyra/security/code-scanning/175

To fix the log injection issue, we need to sanitize the user input before logging it. Specifically, we should remove or replace any characters that could be used to manipulate log entries, such as newline characters. This can be achieved by using the replace method to remove or replace such characters.

1. Identify the lines where user input is logged: lines 33, 53, 65, and 77 in KeycloakRepository.kt.
2. Sanitize the user input by replacing newline characters with an empty string or a safe character.
3. Ensure that the sanitization is applied consistently across all logging statements that involve user input.
