fix: PHPCS — replace multi-line HTML comments, fix verdict-meta array indent + PHP tag

front-page.php:
- Replace 3 decorative multi-line HTML comment blocks (tab+space mixed
  indentation) with single-line <!-- SECTION --> comments; eliminates 16
  'Tabs must be used' PHPCS errors at lines 37-41, 93-97, 127-132

inc/verdict-meta.php:
- Line 37: correct over-indented 'single' key (6 tabs → 3 tabs to match
  array alignment of sibling keys)
- Line 171: split '<?php for (...)' onto two lines so opening PHP tag is
  on a line by itself (WordPress PHPCS requirement)

Both are pre-existing violations now exposed because CI runs PHPCS on all
PHP files (not just changed ones). No functional change.
