Fix SSRFProtect validation options to properly handle Constance settings

[noliveleger]

Description :

This PR addresses an issue where SSRF Protect validation fails to consider the Constance settings correctly. It now strips line break characters from the IP input before performing the SSRF Protect validation.

Testing

• Create a project with RestService (Project > Settings > Rest Services)
• Use local ip (of your host machine) for the endpoint URL (e.g, http://192.168.0.10)
• Add 192.168.0.10 and 192.168.0.11 in SSRF_ALLOWED_IP_ADDRESS in Constance
• Submit data
• It should not raise error ssrf_protect.exceptions.SSRFProtectException: URL "http://192.168.0.10" is not allowed because it resolves to a private IP address (but could still fail because you don't have a webserver which listens on local computer).
