- badge_template_form: fix default field visibility (location off render, pronouns/leads excluded from controls); fix duplicate QR checkboxes by removing orphan show_qr_front/back state vars; reorganize Advanced cfg_json into labeled sub-groups; make all 5 non-Advanced sections collapsible (general starts open, rest collapsed)
- print_controls: add DEFAULT_SHOWN constant so field_shown() uses explicit whitelist fallback instead of showing all fields when no controls_cfg is set
- badges config +page: add Templates navigation button in header (FileText icon)
- templates +page: add back-nav header with ArrowLeft to badges/config, Settings icon, page title
