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.
