Add interactive USA map page with clickable states

[Aharon123]

Motivation

• Provide a simple standalone page that displays a map of the United States and, when a user clicks a state, shows the state's name as requested.
• Support a Hebrew/RTL UI so the page can be used with right-to-left text.

Description

• Added a new file usa-map.html that renders a full US map using D3 and TopoJSON loaded from CDN and maps state FIPS IDs to readable names.
• Implemented a click handler that highlights the clicked state (.state.active) and updates the UI text to בחרת במדינה: <State Name>.
• Included basic styling, RTL layout (lang="he" dir="rtl"), and a fallback error message when the map fails to load.

Testing

• Started a local server with python3 -m http.server 8000 and confirmed the server started successfully.
• Verified the new file was created and committed with git add / git commit (commit succeeded).
• Attempted an automated screenshot via browser_tools.run_playwright_script, but the Playwright run timed out in this environment (failed to capture screenshot).
