feat(auth): add email verification to registration flow

- Add email/email_verified/verification_token/verification_token_exp fields
  to app_users PocketBase schema (pb-init-v3.sh)
- Add SMTP env vars to UI service in docker-compose.yml
- New email.ts: raw TLS SMTP mailer via Node tls module, sendVerificationEmail()
- createUser() now takes email param, stores verification token (24h TTL)
- loginUser() throws 'Email not verified' when email_verified is false
- New /verify-email route: validates token, verifies user, auto-logs in
- Login page: email field in register form, check-inbox state after register
- /api/auth/register (iOS): returns { pending_verification, email } instead of token
- Add pb.libnovel.cc and storage.libnovel.cc Caddy virtual hosts for homelab runner
- Add homelab runner docker-compose and libnovel.sh helper script

+# LibNovel homelab runner

+# Connects to production PocketBase and MinIO via public subdomains.
+# All secrets come from Doppler (project=libnovel, config=prd).
+# Run with: doppler run -- docker compose up -d
+#
+# Differs from prod runner:
+#   - RUNNER_WORKER_ID=homelab-runner-1  (unique, avoids task claiming conflicts)
+#   - MINIO_ENDPOINT/USE_SSL → storage.libnovel.cc over HTTPS
+#   - POCKETBASE_URL          → https://pb.libnovel.cc
+#   - MEILI_URL/VALKEY_ADDR   → unset (not exposed publicly; not needed by runner)
+#   - RUNNER_SKIP_INITIAL_CATALOGUE_REFRESH=true
