[FE-26] Reputation Scores & On-Chain Verification Badges

[mftee]

⚠️ Depends on: [BE-28] Wallet Linking, [BE-21] Reviews Backend — the on-chain verification check and reputation API must exist. [CONTRACT-01] — Reputation contract must be deployed.

Overview

The Soroban reputation contract computes a 0–1000 composite score from on-chain ratings, but this score is never displayed to users. There are also no on-chain verification badges visible in the UI. This issue surfaces blockchain-based reputation data across the platform.

Technical Details

1. On-Chain Reputation Score Display

Add to Carrier Public Profile (/carriers/[id]):

• Below the existing star rating section, add an "On-Chain Reputation" card:
  • Reputation score (0–1000): displayed as a gauge/progress bar (e.g., 750/1000)
  • On-time rate: percentage (e.g., "94% on-time")
  • Total on-chain ratings: count
  • "Verified on Stellar Blockchain" badge with an external link to Stellar Expert for the contract
  • If the carrier has no wallet linked: show "On-chain reputation not available"

Backend endpoint needed (add to CarriersController):
GET /carriers/:id/reputation — queries the Soroban reputation contract's get_score function for the carrier's walletAddress, returns { score, onTimeRate, totalRatings }. If the carrier has no wallet, return { unavailable: true }.

2. Verification Badges

Create a reusable <VerifiedBadge /> component (frontend/components/reputation/verified-badge.tsx):

• Props: type ('email' | 'wallet' | 'carrier'), tooltip (optional)
• Email verified: gray envelope icon + "Email Verified"
• Wallet verified: Stellar logo icon + "On-Chain Verified"
• Carrier verified (by admin): blue shield icon + "Verified Carrier"
• Show in: user menu dropdown, carrier profile cards, bid cards, shipment detail party info

3. Trust Score Panel (Shipper Dashboard — Carrier Selection Context)

On the bids tab of a shipment detail page (from [FE-06]), add a "Trust Score" summary to each bid card:

• DB rating: average stars from GET /carriers/:id/reviews
• On-chain score: from GET /carriers/:id/reputation
• Verified badges: email / wallet / carrier
• Overall trust label: "High Trust" (score > 700 + verified) / "Moderate" / "Unverified"
• This helps shippers make informed bid acceptance decisions

Acceptance Criteria

• Carrier public profile shows the on-chain reputation card with score, on-time rate, and rating count
• If the carrier has no wallet, the card shows "On-chain reputation not available"
• GET /carriers/:id/reputation queries the Soroban contract and returns the score
• <VerifiedBadge /> renders correctly for all three badge types with correct icons
• Verification badges appear in the user menu and on carrier profile cards
• Trust Score summary appears on bid cards in the shipment detail bids tab
• "High Trust" / "Moderate" / "Unverified" label is derived correctly from the score + badge combination
