feat(homepage): SIWS sign-in, unified hover, brand chrome on dashboard

- /get-started gains a Solana Wallet method that drives the existing
  /api/auth/siws/{nonce,verify} endpoints; Playwright can stand in for a
  real wallet via window.__siwsTestSigner.
- All button hover backgrounds unified to brand-black (text inverts);
  removes orange/blue rollover drift across CTAs, nav, and method picker.
- /connected gets a top-left Eliza wordmark header so logo size and
  header padding stay consistent with /get-started; header is pointer-
  events-none so the existing avatar dropdown stays clickable.
- New tests/e2e/aesthetic-audit.spec.ts enforces xs corner rounding,
  unified hover, logo height + nav padding parity, no console errors,
  and full-route screenshot capture; scripts/generate-contact-sheet.mjs
  composes those captures into a single review page. Exposed as
  bun --cwd packages/homepage run test:audit.
