feat(badges): public_access kiosk mode + manager access improvements

- Public (attendee) kiosk: unprinted badges link to /review; printed
  badges show green "Checked in · Nx · First/Last" row (non-clickable)
- Public attendees no longer see Print button (staff-only action)
- Printed badges sort to end of list for public non-trusted users
- Manager access: Print (reprint) and Email Link buttons always visible
  without requiring Edit Mode; main row behavior unchanged
- Empty state wording: context-aware — "Enter your name above to find
  your badge" for public users with no query vs "No badges found" after
  an actual search
- Docs: Epson C3500 fanfold section filled in (was empty placeholder);
  style_href/duplex implementation status corrected in badge templates
  doc; Axonius C3500 layout TODO marked complete
