refactor: remove InvoiceView component and update related email and invoice handling

- Deleted the InvoiceView component to streamline the codebase.
- Updated EmailPreview and SendEmailDialog components to include currency and notes fields.
- Enhanced invoice-form to handle default hourly rates and improved item mapping.
- Refactored email template generation to include notes and currency formatting.
- Adjusted API routers for invoices to calculate totals and handle notes and currency correctly.
