bump mission rewards and add first-clear card logic

- Increased gold rewards for several Imperial missions to improve progression pacing.
- Reformatted `missions.json` for consistency (multi-line arrays).
- Set default starting gold to 300 in `SaveManager`.
- Implemented first-clear-only card rewards in `BattleScene`; subsequent wins grant gold but no duplicate cards.
- Added consolation gold (50% of mission reward) on defeat.
- Fixed `CollectionScene` input priority and improved terminal typing speed and line wrapping.
