Change SecureTelnetLocalPort to support multiple ports

- Changed SecureTelnetLocalPort from single ConfigInt to ConfigSliceString
- Now supports multiple secure local ports: [9998, 9997]
- Updated connection detection to check all ports in the slice
- Allows multiple TLS proxies to forward to different local ports
- Consistent with SecureTelnetPort being a slice
