fix: harden telepresence docker dev flow

[phenix3443]

Summary

• run telepresence through the Docker daemon and route intercepts back to the host via host.docker.internal
• track frontend and server runtime state so status output reflects the active dev setup and config drift triggers a restart
• make frontend leave cleanup resilient when PID files go stale by also stopping matching port listeners

Verification

• bash -n telepresence.sh
• ./telepresence.sh up frontend --frontend admin
• ./telepresence.sh status
• ./telepresence.sh leave frontend
• curl -I http://admin-ppanel-dev.home.arpa
