fix(cli): iterate all apps in config show and add --app filter

Previously `shipnode config show` only rendered `apps[0]` via
`getActiveApp(config)`, hiding every additional app in a workspace.
Split the output into workspace-level sections (SSH, database, redis,
cloudflare) shown once and per-app sections rendered for each app in
`config.apps`. Add a `--app <name>` flag to narrow the view to a
single app.
