fix: verify Cloudflare trace receipts

[creatornader]

Summary

• add a Worker receipt-verification endpoint backed by @atrib/mcp verifyRecord
• replace the receipt verification text chips with icon rows and visible verification results
• tighten the Cloudflare trace header, GitHub mark, risk disclosure, and HITL timeline row to match the reference layout

Tests

• pnpm --filter @atrib/cloudflare-approval-trace typecheck
• pnpm --filter @atrib/cloudflare-approval-trace test
• pnpm --filter @atrib/cloudflare-approval-trace test:browser

Visual QA

• captured local 1536x1024 HITL and verified-state screenshots
• checked for horizontal overflow and flagged clipped controls
