* FileUpload Component
* Story 1.16.3: Generic File Upload Service
* ADR-002: Generic File Upload Service Architecture
*
* Reusable file upload component with drag-and-drop support
* Uses generic /api/v1/logos endpoints - works for any entity type
*
* Features:
* - Drag-and-drop file upload
* - File type and size validation
* - Upload progress indicator
* - Preview uploaded file
* - Remove uploaded file
* - Error handling with user-friendly messages
*
* Usage:
* <FileUpload
* currentFileUrl={logoUrl}
* onUploadSuccess={(data) => setLogoUploadId(data.uploadId)}
* onUploadError={(error) => console.error(error)}
* />
