Three changes to fail fast instead of silently degrading:
1. GameService.create_game: Raise GameCreationError when energy card
definition not found instead of logging warning and continuing.
A deck with missing energy cards is fundamentally broken.
2. CardService.load_all: Collect all card file load failures and raise
CardServiceLoadError at end with comprehensive error report. Prevents
startup with partial card data that causes cryptic runtime errors.
New exceptions: CardLoadError, CardServiceLoadError
3. GameStateManager.recover_active_games: Return RecoveryResult dataclass
with recovered count, failed game IDs with error messages, and total.
Enables proper monitoring and alerting for corrupted game state.
Tests added for energy card error case. Existing tests updated for
new RecoveryResult return type.
