Replace worker's plain HTML table with the same a-table used by master,
fixing inconsistencies: missing role column, no error ellipsis, dead-code
empty state ternary, and duplicate a-empty elements.
Self-closing custom elements (<a-empty />) are invalid in HTML5
in-DOM templates. The browser treats them as opening tags, causing
subsequent sibling elements to become children. This made the
worker's node info table a child of the hidden <a-empty>, so it
never rendered when nodes.length > 0.
- ShouldBindJSON → ShouldBind with form tags (axios sends url-encoded)
- dbType dropdown value "mysql" → "mariadb" to match backend
- Replace inline styles with theme-aware CSS classes for dark mode
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)
