Bug: terminal fails to open with LND custom node

[Abdulkbk]

Describe the bug
When using a custom-built LND image in a Polar network, the terminal window (launched via the "Terminal" button in the UI) opens for a fraction of a second and immediately closes. This prevents any CLI interaction with the custom node.

To Reproduce
Steps to reproduce the behavior:

1. Build a custom LND Docker image (e.g., using a custom Dockerfile with specific user/group configurations).
2. Add the custom image to Polar via Settings > Docker Images.
3. Create a new network and add the custom LND node.
4. Start the network.
5. Click on the node and click the Terminal tab or button.
   The terminal window pops up and crashes/exits instantly.

Expected behavior
The terminal should remain open and provide a functional shell session inside the running container.

Desktop (please complete the following information):

• OS: macOs 15.2
• Polar Version: 4.0.0
• Docker Version: 28.0.4
• Docker Compose Version: 2.34.0

Additional context
I haven't tried this with other node implementations aside LND.

The Dockerfile used can be found here.

Hey @Abdulkbk, do you plan on proposing a fix for this? If not, can you provide the Dockerfile you are using so the issue can be reproduced.

Sure, I will propose a fix. I also updated the issue description with the Dockerfile incase someone wants to reproduce it.
