feat: CI/CD Auto-Deployment Workflow (GitHub Actions compatible)

AUTOMATIC DEPLOYMENT VIA GITEA CI/CD

Workflow: .gitea/workflows/deploy.yml

Trigger:
  - Push to main branch
  - Changes in src/, frontend/, publish/, frontend/dist/
  - Manual workflow dispatch

Pipeline Stages:

1️⃣ BUILD STAGE (ubuntu-latest)
   ✅ .NET 10 SDK setup
   ✅ Backend restore → build → test → publish
   ✅ Node.js + pnpm setup
   ✅ Frontend install → typecheck → test → build
   ✅ Artifacts upload (publish/, frontend/dist/)
   Duration: ~3-5 minutes

2️⃣ DEPLOY STAGE (requires secrets)
   ✅ SSH key setup
   ✅ Backend deployment to /opt/kartsell/
   ✅ Frontend deployment to /var/www/kartsell/frontend/
   ✅ Nginx configuration auto-generation
   ✅ Service restart (systemd)
   ✅ Health verification (frontend + API)
   Duration: ~2-3 minutes

3️⃣ MONITOR STAGE
   ✅ Phase 1 status check
   ✅ Job 893 autonomous monitoring confirmation

Required Gitea Secrets:
  DEPLOY_HOST: production-server.com
  DEPLOY_USER: deploy
  DEPLOY_SSH_KEY: SSH private key (ed25519 format)

Setup:
  1. Go to repository settings
  2. Add Actions Secrets:
     - DEPLOY_HOST (e.g., prod.example.com)
     - DEPLOY_USER (e.g., deploy)
     - DEPLOY_SSH_KEY (generated with: ssh-keygen -t ed25519)
  3. Ensure /etc/systemd/system/kartsell-api.service exists on prod server

Workflow:
  - Commit to main
  - CI automatically: Build backend + frontend
  - On build success: Auto-deploy to production
  - Health checks verify deployment
  - Post comment with deployment status

Result: Full automation from push to production LIVE ✅

Safety:
  - Runs only on main branch
  - Requires successful build+tests
  - SSH key never exposed
  - Health verification prevents bad deploys
  - Reversible (manual rollback easy)

Timeline:
  Commit → Build (5min) → Deploy (3min) → LIVE (8min total)
