Add: Activate watchlist button integration

- Load watchlistButton.js in manifest content_scripts
- Call watchlistButton.display() after float display is created
- Adds '👁️ Add to Watchlist' button to all items with float data

Users can now add items to their SteamLedger watchlist directly from Steam!
