When user traffic quota is exceeded, services are paused with
ForceClosePortConnections to kill active connections. However,
when admin resets quota and resumes services, the resume logic
was missing this cleanup, causing "address already in use" errors.
Changes:
- Add ForceClosePortConnections call in resumeServices (socket & api)
- Add ForceClosePortConnections call in resumeService (api single)
- Increase wait time from 100ms to 500ms for port release
Fixes#387
