bug: emoji wallet icons render unreliably on some platforms

[nanaf6203-bit]

Summary

src/components/WalletModal.tsx defines wallets with raw emoji bytes that render as '?' on some Linux/Windows configurations.

Affected area

src/components/WalletModal.tsx lines 211-235 (icon: '🦊', etc.)

Steps to reproduce

Open the wallet modal on a system without the colour-emoji font installed; icons collapse to monochrome squares.

Expected behaviour

Replace with inline SVG icons (lucide-react or a shared brand-icons component) for cross-platform correctness and better a11y.

Acceptance criteria

• Replace raw emoji with extracted SVG icons.
• Add a title / aria-label describing the wallet.
• Cypress visual test snapshots the icons.
