###Context
Because of how the editing statistics were broken out, we've ended up missing the "Your impact" heading for our first release. There is also no gradient background, causing a less than ideal state in some themes, and lack of visual separation between summary stats and timeline

###Task
[] Add "Your impact" section heading above Total impact across projects module T407676. Do not add "On X Wikipedia" yet
[] Do not show the "Your impact" header if someone does not have any data for the "Total edits across projects" Module
[] Stretch the current blue gradient to that it ends right above Timeline ([[ https://www.figma.com/design/2ShBsmgWuzsDAeTafyKzg6/iOS---%3E-Activity-Tab?node-id=355-1631&t=eh5IXvGlT7je0gRo-4 | Figma ]] was updated on Dec 8)
