fix: [A11Y] Add labels/tooltips for top-right icon controls (closes #703 )

- Add aria-label to all top-right controls (Atlas button, Bannerlord status, Agent Thought Stream) - Add role attributes (status, log) for screen reader semantics - Add aria-live for dynamic content (Agent Thought Stream) - Add aria-hidden to decorative icons (emoji icons, status dots) - Add aria-label to all CLOSE buttons across overlays (vision, portal, memory, session room, atlas) - Add CSS tooltip system using data-tooltip attributes - Tooltips appear on hover and keyboard focus (focus-visible) - Add focus-visible keyboard navigation ring for all interactive controls - Add aria-label to controls hint and Hermes status indicator - Mark decorative elements with aria-hidden First-time users can now infer what each control does via hover tooltips and keyboard focus.
