Smart Timer Pro v3.0.1

• Fixed: the External Sync window now closes for good when pressing X (no auto-reopen)
• The OPEN DISPLAY button toggles between OPEN DISPLAY and CLOSE DISPLAY (sync timer and second timer)
• The external sync timer now shows exactly HH:MM:SS:MS (2-digit hours:minutes:seconds:hundredths) on the presenter, the GUI card and Companion
• Removed the START/PAUSE/RESET buttons from the External Sync Timer card
• Light-blue buttons across the app now use a darker neutral blue so the white text is clearly readable
