feat: Integrate advertising data and dashboard

Adds functionality to process and display advertising data alongside sales data. This includes: - Introducing a new `AdvertisingDashboard` component. - Modifying `FileUpload` to accept advertising CSVs. - Updating `App.tsx` to manage and display both sales and ad data. - Enhancing `dataProcessor.ts` to handle advertising CSV parsing and merging. - Adding a `MegaphoneIcon` for advertising-related UI elements. - Defining new types for advertising records and combined KPIs.
