perf(services-registry): Optimize RPCD handler for 200+ vhosts
Was timing out with 199 HAProxy vhosts due to ~600 UCI calls. Optimizations: - get_haproxy_vhosts(): Single uci show + awk parsing instead of per-vhost uci -q get calls (600 calls → 1 call) - get_init_services(): Check only key services, use symlink detection instead of executing init scripts - get_metrics_summary(): Read CrowdSec data from cache file instead of slow cscli commands Result: Handler now responds in <1s with 204 published services.
