ASINs that have ad spend but no corresponding sales data

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.
Adds papaparse as a dependency and updates the data processing service to use it for more robust CSV file parsing. This replaces manual CSV parsing logic with a dedicated library, improving reliability and handling of various CSV formats.
Also renames the `MoversIcon` to `TrendingIcon` to better reflect its usage in indicating trending performance metrics.
Sets up the project with Vite, React, Tailwind CSS, Gemini AI integration, and necessary dependencies for data analysis. Includes initial configuration for TypeScript, Tailwind, and project metadata.
