Fix what the second CI round found

• Two phpstan.neon files had a duplicated key. Merging the branch with
  main put a second ignoreErrors / reportUnmatchedIgnoredErrors under
  parameters: -- git merges that cleanly because neither side touched the
  other's lines, and NEON then refuses to load the file at all. PHPStan exits
  with its usage banner rather than an analysis, so the job fails without ever
  naming a rule. error-pages and package-scaffolder are folded back to one
  declaration each.

• Orphaned @var list<string> docblocks. Deleting the $commandAliases
  properties left their docblocks sitting above the next method, where
  PHPStan reports PHPDoc tag @var above a method has no effect. Five in
  product-demo-mode.

• Pint drift, resolved at the version CI actually installs. CI resolves
  laravel/pint 1.32.1; a long-lived local vendor/ had 1.30.5, and the two
  disagree about binary_operator_spaces. Checking against the old one is the
  same false green as checking against the wrong config -- so this ran 1.32.1.

• console: PHPStan proves the property_exists($this, 'commandAliases')
  guard false, because it only sees the subclasses inside src/ and none of
  them declare it. The property belongs to the CONSUMING command -- a trait
  and a using class cannot both declare it with different defaults -- so the
  guard is exactly right and the finding is scoped away with that reason.
