fix: resolve undefined variable bugs (phpstan variable.undefined)

- AdminReportController: fix closure param name and remove reference to
  undefined $meta variable
- GroupsPostController: replace $status with $gp (the actual GroupPost
  variable in scope)
- PortfolioController: replace undefined $metadata with null
- DeleteWorker: remove Cache::set() call with undefined $key
