Fix búsqueda en tiempo real, paginación, OneSignal, bancos/categorías y vistas auth

- ajaxcrud.js: fix race condition en búsqueda, abort de requests en vuelo
- Layout: mover @yield('js') después de app.js para corregir orden de carga
- Paginación: useBootstrapFour() + eliminar wrappers <ul> duplicados en 17 vistas
- OneSignal: migrar de UserTag iChamba_ID a ExternalId en controladores
- API: agregar endpoint GET /api/banks y campos rfc/bank/bank_account/fee en hero()
- Seeders: BanksSeeder (239 bancos) y CategoriesSeeder (100 categorías)
- Auth views: corregir padding/scroll en register, login, password reset
