fix: repair supply chain workflow triggers and crowdsec test script

Updated supply-chain-pr.yml to run on main/develop/feature branches
Injected required API key into crowdsec startup test to prevent config panic
Hardened test script to handle missing tools (pgrep) and optional LAPI runtime
Ensures consistent security validation in both CI and local dev environments
