Coding Standards: Fix alignment and PHPCS ignores in reaction support.

- Fix double-space alignment warning in test file (line 4702).
- Extend phpcs:ignore directives in prefetch_reaction_summaries() to
  cover WordPress.DB.PreparedSQLPlaceholders.ReplacementsWrongNumber,
  acknowledging PHPCS cannot count placeholders through the spread
  operator.

See #63191.
