Describe the bug

When using 'Classic' bitcoin denomination setting, an error is seen due to use of float instead of integer:

Transaction Failed
Failed to estimate channel order fee.
[{"type":"Body","errors":{"issues": [{"code":"invalid_type","expected":"integer","received":"f loat","message":"Expected integer, received float","path": ["IspBalanceSat"]}],"name":"ZodError"}}]

1. We should never show this error because we are passing the expected value format to lsp
2. We should handle errors like this in a user-friendly way. Never expose the raw response.

Reproduce

1. Using 'Classic' Bitcoin Denomination (in the general settings)
2. Attempt CJIT fllow: Advanced -> Lightning Connections -> Add Connection -> Use Other Wallet
3. Observe immediate toast error
