ui: scale nav wordmark to match logo height

[proofmancer]

Summary

Bump the `argus` wordmark in the header from `text-sm` (14px) to `text-xl` (20px) and add `leading-none` so the text height collapses to the glyph height — matches the `h-5` (20px) mark.

Test plan

• Header: mark and wordmark visually sit on the same row, same height
• No layout shift on mobile
