Fix Tailwind CSS class typo in PolicyBanner button

[madisoncarter1234]

Summary

Fixes a typo in the PolicyBanner component's button className where Tailwind CSS classes were concatenated without proper spacing.

Changes

• Fixed transition-allactive:bg-[#06318E] → transition-all active:bg-[#06318E]
• Added missing space between transition-all and active:bg-[#06318E] classes

Impact

This ensures:

• Tailwind CSS properly parses and applies both classes
• The active state background color (#06318E) is correctly applied when the button is clicked
• The transition animation works as intended

Testing

The fix can be verified by:

1. Inspecting the button element to confirm both classes are present
2. Clicking the button to verify the active state styling applies correctly

Closes #2502
