Introduces an exportOrdersToCSV function in lib/api-client.ts to allow exporting orders by status as a CSV file. Updates various UI components to use the '•' (bullet) symbol instead of '·' (middle dot) and replaces some emoji/unicode characters for improved consistency and compatibility. Also normalizes the 'use client' directive to include a BOM in many files.
Moved dashboard path check from KeepOnline to a new KeepOnlineWrapper component for cleaner separation of concerns. Introduced a reusable useKeepOnline hook to encapsulate the online status update logic. Updated layout to use KeepOnlineWrapper and simplified KeepOnline. Minor cleanup in broadcast-dialog.tsx.
