Campaign

- Talent Tree now highlights unspent points; stars once again represent missions cleared.
- Clarified mission bonus messaging and permanent rewards.
- Shops now allow you to skip if you can't afford anything.
- Fixed campaign progress carrying incorrectly between missions and other game modes.
- Improved tutorial flow, completion messaging, and pause popups.
- Added a persistent objective log for tutorial.

UI & Quality of Life
