v-else on <table> element was not recognized by Vue template compiler,
causing the worker node info table to never render. Use v-if="nodes.length > 0"
instead to ensure the table renders when data is available.
- Replace a-descriptions/a-descriptions-item with plain HTML table in
nodes.html — the components were missing from the antd.min.js bundle
due to tree-shaking, causing the worker node view to render empty
- Fix ensureDefaultNodeSettings to write defaults to both "node" and
"other" groups for backward compatibility (tests were failing)
