fix: style for icon[loc=right]

[ildar170975]

When a name is hidden and align_icon: right, we can see an icon left-aligned:

  - type: custom:mini-graph-card
    entities:
      - sensor.xxx
    show:
      name: false
    align_icon: right

After the fix:

While this seems a straightforward fix, I'm wondering why align_icon: state also right-aligns but uses a different CSS. Should this be consistent? Or is there a reason, it's different?
