[CLAUDE] Rebrand: 3 domain huypham.vn → solutions.com.vn + migrate script

User request: anh trỏ 3 subdomain mới về VPS IP 103.124.94.38:
  - api.huypham.vn        → api.solutions.com.vn
  - admin.huypham.vn      → admin.solutions.com.vn
  - user.huypham.vn       → eoffice.solutions.com.vn

Verified DNS: cả 3 resolve 103.124.94.38 ✓

Update 17 file repo:
FE (4): fe-admin/.env.production + fe-user/.env.production
        (VITE_API_BASE_URL → https://api.solutions.com.vn)
        fe-admin/src/lib/{api,realtime}.ts + fe-user equivalents (comment)
BE (1): appsettings.Production.json.example — CORS AllowedOrigins
CI/CD (1): .gitea/workflows/deploy.yml — smoke test URL
Scripts (3): setup-iis-sites (DomainApi/Admin/User), setup-ssl (3 host),
             deploy-all (verify curls)
Docs (5): STATUS, HANDOFF, PROJECT-MAP, vps-setup, gotchas
Skill (1): iis-deploy-runbook — 3 site table + description
Email admin@huypham.vn giữ nguyên (Let's Encrypt contact — không phải
domain serve).

Thêm scripts/migrate-domains.ps1 — 1-shot VPS migration:
  1. Pre-flight: resolve DNS 3 domain → verify IP VPS khớp
  2. Add HTTP binding mới cho 3 IIS site (giữ binding cũ làm fallback)
  3. Run win-acme xin 3 cert Let's Encrypt qua HTTP-01 challenge
     (auto add HTTPS binding + http→https redirect)
  4. Verify /health/live + /health/ready + 2 FE endpoint
  5. (Optional -RemoveOld) xóa binding huypham.vn sau verify OK
Rollback: nếu fail, binding cũ vẫn active → site serve qua huypham.vn.

Anh chạy trên VPS:
  cd C:\solution-erp\scripts  ;  .\migrate-domains.ps1
  # Sau 1-2 ngày verify stable:
  .\migrate-domains.ps1 -RemoveOld -SkipCert

+# Migrate domains from *.huypham.vn to solutions.com.vn (Phase 6+ rebrand).
+# Run trên VPS với admin privilege. Idempotent — chạy lại nếu fail giữa chừng.
+#
+# Workflow (3 IIS sites):
+#   1. Add binding mới cho domain mới (*:80 + *:443 với cert self-signed tạm)
+#   2. Run win-acme xin cert Let's Encrypt qua HTTP-01 challenge (port 80)
+#   3. Verify /health/ready + /health/live qua domain mới
+#   4. Remove binding cũ (*:huypham.vn + *:user.huypham.vn) — OPTIONAL via -RemoveOld
+#
+# Usage:
+#   .\migrate-domains.ps1                           # giữ binding cũ, thêm mới
+#   .\migrate-domains.ps1 -RemoveOld                # xóa binding cũ sau verify

+# Prereq:
+#   - DNS 3 domain mới đã trỏ 103.124.94.38 (user confirm)
+#   - Port 80+443 firewall open cho internet
+#   - win-acme đã cài (script setup-ssl.ps1 cài sẵn)
