Changed export success/error messages to match the style used for thinking level changes:
- Use Spacer(1) instead of empty Text for proper blank line spacing
- Use chalk.dim() for success message instead of chalk.green()
- Add left padding (1, 0) to match other system messages
- Removed checkmark/x symbols for cleaner look
Now "Session exported to: filename.html" appears dimmed with proper spacing, just like "Thinking level: off"
