Pull request overview

Fixes CarPlay entity icon rendering by ensuring HAEntity.getIcon() uses the resolved Material Design Icon (custom attribute icon or domain-based fallback) instead of always returning the default bookmark icon, and adds regression tests for the expected fallback behavior.

Changes:

• Update HAEntity.getIcon() to use getMDI() as the base icon source.
• Add unit tests verifying CarPlay icon selection for (a) no custom icon and (b) custom attributes.icon present.
