…ton) dropping the connection Users with Norton 360 installed found that if there is no traffic over the WebSocket for 60s, it gets dropped. This appears to be that the connections are proxied (even if all scanning is disabled) and "idle" connections are dropped. This forces traffic ever 15s which will prevent them from dropping the connection. Fixes #5794

[nitpick] The test suite only covers the happy path (sending pings). Consider adding tests for edge cases such as:
- Socket closing before/after ping starts - verify cleanup happens correctly
- Socket error during ping - verify error handler clears the interval
- Attaching ping to an already-open socket vs. a connecting socket
These additional tests would ensure the cleanup logic (removeListener calls) and error handling work correctly.
