Revamp game pausing and input handling. Fix minigame tutorial and end sequence. (#39)

- Revamp pausing and centralize management in GameManager
- Switch Pause implementation to be counter-based to solve corner case of multiple pause requests
- Remove duplicated Pause logic from other components
- Add pausing when browsing the card album
- Fully deliver the exclusive UI implementation
- Spruce up the MiniGame tutorial with correct pausing, hiding other UI
- Correctly unpause after showing tutorial
- Fix minigame ending sequence. The cinematic correctly plays only once now
- Replaying the minigame works
