v1.4.6: Add Copy URL Mode

New Feature: Copy URL Mode

Added a new mode that copies NFC tag URLs to the clipboard without opening the browser. Perfect for quickly retrieving URLs from tags for use in other applications.

What's New

• Copy URL Mode button - New cyan button on the control panel (keyboard shortcut: Ctrl+Shift+R)
• URL display box - Shows the copied URL when in Copy URL Mode for easy verification
• Voice announcements - TTS feedback when switching to Copy URL mode and when URLs are copied

How It Works

1. Click "Copy URL Mode" or press Ctrl+Shift+R
2. Present an NFC tag
3. URL is copied to clipboard and displayed in the app
4. Paste anywhere you need the URL
