#### Description

##### **Summary**

This update introduces new functionality to the `secfilter` module, enabling the removal of entries from both the Blacklist and Whitelist. It also includes automatic detection and removal of duplicate values from these lists.

##### **Details**

* Users can now remove specific entries from the Blacklist or Whitelist based on type (e.g., IP, domain, user) and a given value. * Supports removal of single or multiple matching entries in one operation.

##### **Benefits**

- Improves the usability and flexibility of the `secfilter` module by allowing fine-grained control over list management. - Ensures that the Blacklist and Whitelist are kept clean and free from redundant entries. - Enhances performance by reducing unnecessary duplication in the lists.

##### Testing This feature was tested using `kmcmd` commands in various scenarios: - Removing the **first element** in the list. - Removing an element from the **middle** of the list. - Removing the **last element** in the list. - Removing **all matching elements** in the list.

In all cases, the commands worked correctly, and the lists were updated and cleaned as expected.
