fix(emails): sharpen wordmark, add clear space, and standardize footer icon sizes (#5802)

- Re-rasterize the email wordmark from vector at 4x with baked-in vertical clear space so it renders crisp and is no longer clipped at the top/bottom; size the header logo box to 68x41 to match.
- Normalize the footer social icons (X, LinkedIn, GitHub, Slack) to a uniform cap-height on 40x40 (2x) canvases so they read as the same visual size.
- Add display:block + border:0 to the linked social icons to avoid Outlook's inline-image gap and blue link border.
