Common banner text is centralized and doesn't show icon

<Common.banner
          type="danger"
          id="canvas-banner-limit"
          message={@limit_banner_message}
          class="absolute"
          icon={true}
          centered={true}
/> 

Version number

2.8.2

I have reproduced this locally on main:

• Yes
• No

To Reproduce Steps to reproduce the behavior:

1. On the Billing App, on branch ai-assistant-limiter uncomment this banner on the workflow_live/edit.ex
2. Set @default_ai_limit to small value in subscriptions_usage.ex
3. Send some AI questions/queries until the limit.
4. See error that the banner text is not centralized and doesn't show the icon.

Expected behavior A clear and concise description of what you expected to
happen.

icon and centered boolean attributes are considered.

Start with the Common.banner usage in workflow_live/edit.ex and the limit setup in subscriptions_usage.ex, following the reproduction steps on the ai-assistant-limiter branch. Inspect how the banner handles the icon and centered attributes, then verify that the reproduced limit banner displays its text, icon, and centered layout as expected.
