Post-launch fixes from live testing (Gitea #22):
- Feed/explore postInclude never selected Pet.isVerified, so PostCard only
ever rendered the new Sponsor badge, silently dropping Verified next to
it. Both now render side by side, matching the pet profile page.
- /unterstuetzen had no navigation entry anywhere -- added to the desktop
Sidebar (mobile bottom nav is a fixed 5-tab bar, left alone per scope).
- Admin users list showed no sponsor status at all -- SPONSOR badge added
next to the user_XXXX id, same pattern as the existing BANNED/
SHADOWBANNED badges.
