Bazaar is browsable despite Privacy Mode active by default

This toggle is available for default Foundry Filepicker sources User and Core, but not for Bazaar and Assets Library

This is because Privacy Mode is always turned on on Forge for Bazaar and Assets Library sources, and relies on an API key to share a specific folder from the Forge Assets Library.

Despite privacy mode being turned on, however, it's possible to browse assets on the Bazaar source.
(Note the blue tint that implies that the asset is under private mode, even if it is visible. This screenshot was taken from a player that has FilePicker browse permission in Foundry permissions.)

Making the Bazaar source browse-able despite being under Private Mode might be necessary so that assets referenced by relative paths are able to check if their path exists on the Bazaar (such as for jb2a or large asset packs). But showing the light blue private mode indicator but not actually hiding the assets from players with FilePicker permission is inconsistent and might cause confusion.

We should clarify that the Bazaar assets need to be browsable, if there is a technical requirement. If there isn't then the Bazaar assets shouldn't browsable while under private mode.
