Update VS Code settings

- "eslint.validate": [ "javascript" ] is no longer needed
    (Modern versions of the ESLint VS Code extensions
    automatically validate JavaScript files by default.)
- Configure editor to use tabs instead of spaces per ESLint rules
- Switch to VS Code's built-in HTML formatter
- Add EJS file associations for proper syntax highlighting
- Add recommended extensions for development workflow
