Fix coding standards

Assigning to myself as I'm triaging all RTBC issues.

Thanks for the issue, patches, and reviews.

Unfortunately, this is definitely very outdated. See attached output from:

phpcs --standard=Drupal --extensions=php,module,inc,install,test,profile,theme,css,info,txt,md,yml .

Also note 2 related issues:

📌 Missing doc comment Needs work
🐛 Line exceeds 80 characters Needs work

Postponing this one for now until some others get handled first:

📌 Missing doc comment Needs work
🐛 Line exceeds 80 characters Needs work
🐛 Missing parameter type RTBC
