critical: fix MODULE_NOT_FOUND from missing theme/colors.json import

[EmeditWeb]

Problem

Six legacy component files use require(\../../theme/colors.json') which does not exist in the project. The actual colors are in constants/colors.ts.

Files that will crash:

• components/pages/PayScreen.tsx:7 — CRITICAL
• components/pages/InvestScreen.tsx:17 — CRITICAL
• components/pages/SettingsScreen.tsx:6 — CRITICAL
• components/shared/Header.tsx:5 — CRITICAL
• components/shared/BottomBar.tsx:5 — CRITICAL
• components/shared/NotificationsPanel.tsx:25 — CRITICAL

These components are imported from App.tsx via MainLayout → InvestScreen.

User impact: The app crashes at startup with a MODULE_NOT_FOUND error. Users cannot use the app.

Before Starting

Read: context/architecture-context.md, context/code-standards.md

Root Cause

These are legacy components from a previous branding era ("Trust Up"). They were never removed or updated after the project rebranded to StepFi and migrated to Expo Router.

What To Build

1. Fix the require paths to import from constants/colors.ts
2. Replace all Ionicons icons with lucide-react-native
3. Verify the entire component set loads without errors

Better approach: Remove these legacy components entirely since they are dead code. The Expo Router app in app/ already provides the same functionality.

• components/pages/SettingsScreen.tsx — fix or remove
• components/shared/Header.tsx — fix or remove
• components/shared/BottomBar.tsx — fix or remove
• components/shared/NotificationsPanel.tsx — fix or remove

Acceptance Criteria

• No runtime crashes from missing theme/colors.json
• App starts without errors
• Expo export passes

Mandatory Checks

• context/ files read
• npx expo export --platform web passes
