Add feature to send PDF files to a webhook for processing

Implement a new API endpoint `/api/bap/send-webhook` that accepts PDF uploads and recipient data, processing them via a n8n webhook. This includes client-side state management for file uploads and processing feedback, along with server-side validation and error handling. Dependencies for `form-data`, `multer`, and `node-fetch` were also updated.
