feat: badge print UX improvements — chrome toggle, banner width, overlap fix, header centering

- Replace ae_comp__badge_obj_view_v2 with ae_comp__badge_obj_view (consolidated component)
- Add hide-chrome toggle ([H] shortcut + button) to hide site nav/footer/sys bar for clean print workspace
  — syncs $ae_loc.sys_menu.hide + $ae_sess.disable_sys_nav/footer with restore-on-unmount
- Add banner_full_width toggle (default true=100% width, false=natural pixel size for calibration)
- Center badge header image (display:block; margin:0 auto) — was left-aligned when narrower than badge
- Fix controls panel overlap: move from bottom-0 to bottom-24 to clear sys bar (84px tall)
- Add [H] keyboard shortcut for chrome toggle (guards against focus in inputs)
- Persist hide_chrome and banner_full_width in ae_badge_print_tweaks localStorage key
- Add sample header image assets (calibration SVG/PNG, hex blue SVG/PNG, demo PNG)
- Update badge PVC CSS layout and module docs
