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.
