Subject: [PATCH] feat(downloads): let admins set a quota for any user, not
 only downloaders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The admin System tab only listed users with an existing footprint, so a quota could be set only
after someone downloaded something. Add a 'Set a user's quota…' picker (over /api/admin/users,
excl. demo) beside the Per-user footprint heading that opens the quota editor for ANY user — the
quota GET/PUT endpoints already resolve defaults + create a row on demand, so no backend change.
Also show an empty-state line when no one has a footprint yet. i18n en/hu/de.
