Revamp header layout

[Eric-Arellano]

This improves the header:

• Makes all touch targets at least 44px, the accessibility minimum
• Moves copy link icon to the header
• Removes the "Parking Lot Map" text
• adds a teal border underneath

It also adds more explanatory text to the header in the scorecard, now saying "Parking lots in City, ST" to better explain what people are seeing.

Removing the "Parking Lot Map" text achieves two things:

• Allows us to fit the header on a single line, even on mobile. This allows more screen real estate for the map itself and scorecard
• Improves information hierarchy. The name of the map is not as important as the map itself and explaining what you're seeing on the map (i.e. the unexpanded accordion)

People will still see the name of the map because it's often accessed from the resources folder with all the additional context.

Finally, this improves the size and positioning of the donate button.
