fix(wallet-web): visible brand marks, centered auth card, spaced CTAs, no cross-brand chain leak

- brands/{lux,zoo,hanzo}.svg: real marks (violet Lux prism, colorful Zoo venn,
  Hanzo block-H). The prior rect fill="currentColor" + black glyph collapsed to a
  solid black square in the light-theme header (currentColor is the dark text color).
- gui-stub tokenize(): numeric Tamagui space/size tokens ($3/$6/$10) now resolve to
  px on a 4px scale. They were mapped to undefined CSS vars (var(--3)), so every
  gap/padding/fontSize was silently dropped — the source of the gap-less "button
  blob" (colliding radii) and the top-anchored auth card.
- Welcome: plain inline-styled, viewport-centered card with a max-width panel, the
  brand mark, and 44px CTAs separated by real gaps (matches AppShell/Callback pattern,
  independent of the unresolved Tamagui token contract).
- overlays/{lux,zoo,hanzo}/brand.json: drop sibling first-party L1s from the chain
  selector. Zoo no longer lists "Lux C-Chain"/"Hanzo"; each brand keeps its own
  networks + neutral public EVMs (Ethereum/Arbitrum/Base/Polygon/Avalanche).
