refactor(support): group Bouncer, Media, Setup files into subdirs

Finishes the Support/ consolidation pass: the three remaining root-level files get grouped into purpose-named subdirs, matching the shape the Pdf/, Hashids/, Update/, and Module/ subdirs took in the earlier sweep.

- BouncerDefaultScope → Support/Bouncer/ (Bouncer-specific authorization scope)

- CustomPathGenerator → Support/Media/ (Spatie MediaLibrary path generator — media config references it from config/media-library.php)

- InstallWizardAuth → Support/Setup/ (folded into the existing Setup/ subdir alongside EnvironmentManager, FilePermissionChecker, InstallUtils, RequirementsChecker — it's install-wizard-flow state)

4 consumer files updated (AppServiceProvider, LoginController, UseInstallWizardTokenAuth middleware, config/media-library.php). app/Support/ root is now completely empty of standalone PHP files except helpers.php.
