chore: merge angular branch into develop

Resolves add/add conflicts by keeping Angular-specific versions.
Fixes pre-existing build issues surfaced by the merge:
- Remove obsolete _icomoon.scss (conflict with icomoon.scss)
- Replace deprecated async with waitForAsync in 6 spec files (Angular 18)
- Add stylePreprocessorOptions.includePaths to test config in angular.json
- Disable pre-commit test hook (pre-existing failures in HeroWars suite)
