fix: move proxy-port properties to proxy plugin and fix CI failures

- Move proxy-port and proxy-ssl-port properties from ports plugin to
  proxy plugin where they conceptually belong
- Generalize proxy:set to handle any property (matching ps:set pattern)
  instead of only handling the type property
- Fix apps:set --global flag parsing (pflag treats --global as a flag,
  not an argument — must be defined explicitly like ps:set does)
- Add missing property-functions source to scheduler-docker-local
  shell scripts (scheduler-enter, scheduler-run, scheduler-deploy,
  check-deploy, bin/scheduler-deploy-process-container)
- Update nginx-vhosts property references from ports to proxy plugin
- Update tests to use proxy:set for proxy-port properties
