Evaluate hm-aspects shared between OS & Standalone wihout conflicts

[vic]

Fixes #89

[Copilot]

Pull Request Overview

This PR refactors the aspect definition system to enable proper evaluation of home-manager aspects that are shared between OS-integrated and standalone configurations without conflicts. The refactoring unifies the previously separate aspect creation functions and ensures consistent parameter passing throughout the codebase.

Key changes:

• Unified aspect creation from three separate functions (homeAspect, hostAspect, userAspect) into a single makeAspect function with consistent behavior
• Updated parameter passing to include user and home contexts where needed for proper aspect resolution
• Introduced a new mainModule helper function in _types.nix to properly resolve aspects with the correct context
