Fix dashboard card layout, icons, alignment, and memory card visibility

- Docker/VM tiles: wrap containers into columns instead of horizontal scroll
- Add 6 missing ICON_MAP entries + fireflyiii/minecraft icon assets
- Card title icons: align-items flex-start so icons sit beside h3, not below
- Scope .head_bar hide rule to Processor card to stop hiding Memory card header
