Live sidebar badges for Watchlist/Wishlist, update Wishlist icon to star

Sidebar nav badges now update from HTTP polling (every 10s), WebSocket
pushes, and page init — counts stay current regardless of which page
the user is on. Wishlist icon changed from music note to star in both
sidebar and page title to distinguish from Artists page.
