Title: MobileRaker does not support IPv6

Description:

Currently, the MobileRaker application does not support IPv6 addresses. This limitation prevents users from connecting to their 3D printers running Klipper if they are on an IPv6 network.

Steps to Reproduce:

Ensure your network is configured to use IPv6.
Attempt to connect to your 3D printer using MobileRaker.
Observe that the connection fails or the application does not recognize the IPv6 address.

Expected Behavior: The application should be able to connect to 3D printers using IPv6 addresses.

Actual Behavior: The application fails to connect to 3D printers when using IPv6 addresses.

Additional Information:

MobileRaker Version: 2.6.19-440
Klipper Version: v0.12.0-317-gb89d55238 
Operating System: android 14

Screenshots/Logs: [Attach any relevant screenshots or logs that demonstrate the issue]

Possible Solution: Implement support for IPv6 addresses in the MobileRaker application to ensure compatibility with modern network configurations.
