chore: Sonar fixes after detector refactor (#3968)

Blocked by:

-  #3498 

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->

## Summary by CodeRabbit

- **New Features**
	- Enhanced safety in the `DD4hepDetector` class by using const references in loop iterations.
	- Updated sorting mechanism for several vectors to utilize modern C++ practices.

- **Bug Fixes**
	- Adjusted data types in the `Config` struct of the `AlignedDetector` class for better performance and accuracy.
	- Removed obsolete member variable from the `Config` struct in the `AlignedDetector` class.
