Refactor autosave: centralize decision logic and improve readability

- Add RequestAutoSave() wrapper function with centralized filter logic
- Add HasPendingAutoSave() helper for better code readability
- Replace direct QueueAutoSave() calls with RequestAutoSave()
- Consolidate multiplayer and enabled checks in one place
- Improve code maintainability and separation of concerns
