[os-crowdsec] Crowdsec does not start with multi-server setup (26.7)

• I have read the contributing guide lines at https://github.com/opnsense/plugins/blob/master/CONTRIBUTING.md

Describe the bug
When the plugin is setup to listen on 0.0.0.0, the local connection from OPNsense itself fails with
level=fatal msg="crowdsec init: while initializing LAPIClient: authenticate watcher (localhost): Post \"http://0.0.0.0:8080/v1/watchers/login\": performing jwt auth: dial tcp 0.0.0.0:8080: connect: network is unreachable"

If I change it back to 127.0.0.1, OPNsense itself can connect again, but all other connected machines (a NPMPlus LXC in my case) cannot.

This was working without any issues on the previous release, which in my case was 26.1 (the last version before 26.7 was released),

Expected behavior
Crowdsec should start :)

Screenshots
Current, not working settings, found under "https://FIREWALL-IP:8443/ui/crowdsec/general/index#settings"

Environment

26.7.1_1 on amd64
running bare metal on a sophos 125 SG

Start by reproducing the setup in the CrowdSec General settings at the reported UI path, comparing the 0.0.0.0 and 127.0.0.1 listener configurations on OPNsense 26.7.1_1. Trace the local watcher authentication and remote connection configuration to identify why the local connection uses 0.0.0.0; done means CrowdSec starts while both OPNsense and connected machines can connect.
