ESLint was failing with "couldn't find an eslint.config.(js|mjs|cjs) file" due to missing config for ESLint v9's flat config format.

Changes

ESLint Configuration

• Added eslint.config.js with TypeScript, React hooks, and React refresh plugins
• Configured ignores for dist/, node_modules/, and materialize_v13.11.0/
• Relaxed rules for shadcn/ui components to suppress false positives on library patterns

Fixed unused imports

• AIModelSettings.tsx: DialogTrigger
• DashboardStats.tsx: formatLargeNumber
• OrganizationSettings.tsx: Users, replaced any with TeamMember['role']
• TransactionSignDialog.tsx: User
• SendTransactionForm.tsx: XCircle, getRiskColor
• mock-data.ts: TokenBalance

// Before
m.id === memberId ? { ...m, role: newRole as any } : m

// After
m.id === memberId ? { ...m, role: newRole as TeamMember['role'] } : m

Note: This is a frontend prototype with mock data by design. Real blockchain/payment integrations would require backend infrastructure not present in this repository.
