style(phpcs): autofix WordPress-Core violations via phpcbf

Run phpcbf --standard=WordPress-Core across includes/, prautoblogger.php,
and uninstall.php. Fixed 1,362 formatting violations in 75 files:
  - Short array syntax: [] → array()
  - Line breaking for long function calls
  - Consistent indentation
  - Function call parameter alignment

No logic changes; purely mechanical formatting.
