fix: resolve svelte-check warnings (non-IDAA batch)

- Remove dead .field_editing_wrapper CSS rules from element_ae_crud_v2.svelte
  (template migrated to field_editing_wrapper_v2 with Tailwind)
- Fix TS error: use optional chaining on person_obj key in ae_comp__person_obj_tbl.svelte
- Fix state_referenced_locally: wrap data.user init with untrack() in users/[user_id]/+page.svelte
- Replace misused <label> with <span> for visual section headings (a11y) in:
  launcher_cfg_native_os.svelte, launcher_cfg_health.svelte,
  launcher_cfg_local_actions.svelte, launcher_cfg_template.svelte
