Svelte: fix 3 svelte-check warnings (non-IDAA) + Playwright test type error

- ae_comp__badge_print_controls: select_ref_badge_type declared as $state()
  so Svelte 5 tracks DOM ref assignment correctly (was plain let).
- launcher_cfg_section: <svelte:component this={icon}> replaced with
  let Icon = $derived(icon) + <Icon /> — svelte_component_deprecated fix.
- launcher_file_cont: same svelte_component_deprecated fix for FileIcon.
- badge_print_layout.test.ts: inject_idb signature changed from (badge, template)
  to ({ badge, template }) — page.evaluate() passes exactly one argument;
  all three call sites updated to pass { badge: mock_badge, template: mock_template }.
