🎨 Palette: Add dynamic ARIA labels to Connect buttons in KiwiNodeBrowser

[d3mocide]

What: Added dynamic aria-label and title attributes to the "Connect" buttons within the KiwiNodeBrowser component lists.
Why: The buttons previously lacked accessible names specifying their target. Screen reader users traversing the page would only hear "Connect" or "Active" without the context of what node they were connecting to. Adding dynamic labels provides this critical context.
Before/After: Visually unchanged (tooltips added on hover).
Accessibility: Screen readers now announce "Connect to [host name]" or "Connected to [host name]" instead of a generic action string.
