Merge 6848e3ae54 into f3f606a9ce

When skipPrompts is true, config fields without a default value
were silently skipped, leaving them undefined in the collected
config. This caused downstream code to prompt the user or fail
when encountering missing config values.

Now assigns empty string as fallback for fields without defaults
when --yes flag is active, ensuring fully non-interactive install.

Fixes #1803
