🎨 Palette: Enhance sidebar keyboard accessibility and screen reader experience

[billlzzz10]

💡 What:
Added focus-visible styles to all interactive elements within the Sidebar (navigation links, language toggle, and agent status indicators) and improved ARIA attributes for screen readers.

🎯 Why:
Sighted keyboard users need clear visible focus rings to navigate the sidebar effectively. Screen reader users need to be able to focus the agent status indicators and not have decorative icons/tooltips read redundantly.

📸 Before/After:
(See generated screenshot for focus rings)

♿ Accessibility:

• Added focus-visible:ring-2 focus-visible:ring-white/50 focus-visible:outline-none for keyboard navigation on interactive elements.
• Added aria-hidden="true" to decorative icons (Terminal, Globe, nav item icons) and redundant tooltip spans since they are already covered by aria-label.
• Added tabIndex={0} and a descriptive aria-label to agent status indicator bars to make them discoverable.
