feat(editor): Move code editor preferences to settings and add option to expand editor

Add global settings integration and persistent user preferences for
the code editor. Settings are now stored in localStorage and persist
across sessions.

Changes:
- Add theme, word wrap, minimap, line numbers, and font size settings
- Load editor preferences from localStorage on initialization
- Expose global openSettings function for cross-component access
- Add settingsInitialTab state to control which settings tab opens
- Pass initialTab prop to Settings component for navigation

This improves UX by remembering user preferences and allows other
components to open settings to specific tabs programmatically.
