refactor: consolidate obscure_email and browser reset into shared utilities

- Remove 6 local copies of obscure_email(); all now use ae_util.obscure_email()
  (badges list, badge review, badge print, presenter list, presenter detail, session view)
- badge review page: add missing ae_util import
- e_app_sys_bar: replace inline IDB/storage clear implementations with core_func.clear_idb()
  and core_func.clear_all_storage(); adds known-names fallback the inline version lacked
- fix-sw page: replace 110-line inline nuke with core_func.clear_all_storage(log_callback);
  step-by-step logging and countdown UI preserved via BrowserResetLogFn callback
