fix: eliminate all TypeScript any usage across Vue components

Replace 24 `err: any` error handler types with proper `AxiosError<ApiErrorResponse>`
typing. Fix additional `as any` casts and `Record<string, any>` patterns in registration
field components, event settings, and portal layout. Create shared `ApiErrorResponse`
type for portal app.
