Describe the problem
Using the firewall bouncer with a LAPI on another host currently needs manual YAML edits, and the
plugin shows an error because it always checks the disabled crowdsec service.

Describe the proposed solution

• Implement UI support for remote LAPI in the remediation component.
• Check plugin status only for enabled services
