Add inbound email capture via Cloudflare Email Worker

- Cloudflare Email Worker forwards hello@ and nate@ to Gmail and POSTs parsed MIME email to /api/inbound-email as admin inbox entries - New server route authenticates via shared secret and deduplicates by Message-ID before storing inbound emails as contact submissions - Admin inbox shows "email" badge for inbound messages; reply composer opens blank with auto-subject "Re: [original]" and signature preview - Documents setup steps in cloudflare/email-worker.js and .env.example Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
