Fix Health Panel usability issues

- Fixed aria-controls on HealthComponentComponent, HealthInfoComponent, HealthInfoComponentComponent, HealthPanelComponent pointing to non-existing id
- Fixed the tabs not having the role tab on its tabs
- Fixed aria-expanded being set to true when collapsed and backwards for HealthPanelComponent & HealthInfoComponent
- Fixed role="tablist" not having direct role="tab" by adding role="presentation" on the li elements
- Fixed minor alignment issues
