Refactor collectible handling and scoring system

- Introduced `CollectiblePickupContext` and `CollectiblePickupEffect` to streamline the collectible pickup logic in the Player class.
- Updated the `tryPickup` method in the Player class to utilize the new effect system for health, ammo, score, keys, and weapons.
- Refactored collectible classes to implement the new `tryCollect` method, returning a `CollectiblePickupEffect`.
- Enhanced enemy classes to expose score values based on their type.
- Added unit tests for scoring ownership and shareware menu module functionality.
- Updated rendering logic in various renderer classes to use the new mapped picture retrieval system.
- Improved the `WolfClassicMenuArt` class to utilize a more structured approach for image retrieval based on registry keys.
