Every `:report` subcommand now recognizes `--global` as a scope selector that limits the report to globally-configured properties, including in JSON form via `--global --format json`. Previously this combination was rejected because `--global` was treated as an info flag, conflicting with `--format`. The shared `common.ParseReportArgs` helper now returns a `ReportArgs` struct exposing the parsed scope; each Go and bash report selects a global-only flag map when scope is global, and skips per-app verification.
It is not sanitized in json format output as that is used for automation, but this should remove the need to redact any potentially sensitive information that users have in the sink, such as a token.
Closes#8147
Dokku uses a few external images for various bits of functionality, but these must be manually updated every so often due to being referenced in code.
By moving the references to Dockerfiles, we can take advantage of dependabot to issue automatic PRs when they are out of date.
