Fix Windows installer network mode selection not accepting Enter key

[hobostay]

Summary

• Fixed network mode selection in Windows PowerShell installer
• Changed input validation from -not $localChoice to [string]::IsNullOrEmpty($localChoice)
• Users can now press Enter to accept default "local only" mode

Problem

Issue #257 reports that in the Windows installer, the network mode selection prompt doesn't work as expected. When users press Enter without typing anything, the selection is skipped and defaults to "local only" mode without proper interaction.

Root Cause

The condition used to check for empty input was incorrect:

$localChoice = Read-Host "$(Get-Msg 'port.local_only.choice')"
if (-not $localChoice) { $localChoice = "1" }

In PowerShell:

• Read-Host returns an empty string "" (not $null) when user presses Enter
• -not "" evaluates to $false (only empty string is falsy)
• The default value "1" is never applied when user just presses Enter

Solution

Changed to use [string]::IsNullOrEmpty() which correctly handles both $null and empty string cases:

$localChoice = Read-Host "$(Get-Msg 'port.local_only.choice')"
# Handle empty input (user pressed Enter without typing anything)
if ([string]::IsNullOrEmpty($localChoice)) { $localChoice = "1" }

Testing

1. User can now press Enter to accept default "local only" mode (option 1)
2. User can type "2" or "n" or "N" or "no" or "NO" to select "external access" mode
3. User can type "1" or any other input to select "local only" mode

This aligns with the installer's "(press Enter for defaults)" behavior described in the documentation.

The documentation mentions "(press Enter for defaults)" multiple times, and this fix ensures that behavior works correctly in the network mode selection.
