Add combat animations and fix music overlap

- Add monster attack animation (rubber band snap towards player)
- Fix animation direction (now snaps left towards player)
- Add orange highlight on attacking monster
- Fix animation persistence through DOM rebuilds
- Prevent login music playing over game music on refresh
- Check for existing auth before starting login music
