Replace old plugin headers with proper file docblocks, add ABSPATH guards

- open-graph-tags.php: replace Plugin Name header with package docblock
- featured-image-generator.php: same cleanup
- sp-event-permalink.php: same cleanup, normalize indentation to tabs,
  collapse redundant switch cases (league/tournament both map to 'game')
