docs(ci): rewrite setup guide for Gitea Webhook deploy trigger

The previous doc assumed a Gitea Actions workflow (which requires a
self-hosted act_runner that we don't have, hence the 'No matching
online runner with label: ubuntu-latest' error).

The actual setup is much simpler: a Gitea Webhook pointing at the
deploy endpoint. No runner, no workflow file. Setup is one-time in
Settings -> Webhooks -> Add Webhook.

Documents:
- The push -> webhook -> deploy -> EasyPanel flow
- Exact payload URL, method, content type, events
- Test Delivery verification step
- Why Gitea Actions doesn't work without act_runner
- Troubleshooting: push not triggering, build failure modes
  (nixpacks 'No start command', node 20 vs 22), and a curl recipe
  for redeploying without a code change.

+# CI/CD Setup — Deploy via Gitea Webhook
+
+The site auto-rebuilds on every push to `main` via a Gitea **webhook**
+(no Actions runner, no `.gitea/workflows/`, no act_runner required).
+
+## How it works
+
+```
+git push origin main
+      │
+      ▼
+Gitea Webhook (Gitea built-in, not Gitea Actions)
+      │  POST  Content-Type: application/json
+      ▼
+http://110.164.146.47:3000/api/deploy/<token>
+      │  HTTP 200 "Deploying..."
+      ▼
+EasyPanel pulls repo, builds with Dockerfile, redeploys
+```
+
+## One-time webhook setup
+
+In `https://git.moreminimore.com/kunthawat/dealplustech-astroreal/settings/hooks`:
+
+1. Click **Add Webhook → Gitea**
+2. Fill in:
+   - **Payload URL**: `http://110.164.146.47:3000/api/deploy/772d2c3a4a7d8671657c947c059bc1cdc64bd816efb7fbe2`
+   - **HTTP Method**: `POST`
+   - **Content Type**: `application/json`
+   - **Events**: **Push events**
+   - **Active**: ✓
+   - **Branch filter**: leave empty (or `main` to restrict)
+3. Click **Add Webhook**
+4. Test: click the webhook row → **Test Delivery** → **Push events** → confirm
+   **Last Response** is HTTP 200.
+
+Done. From now on every push to main redeploys automatically.
+
+## EasyPanel service requirements
+
+The service on the panel side (`project=customerwebsite`,
+`service=dealplustech-astro`) must be:
+
+- **Type: `app`**
+- **Source: Git**, branch `main`
+- **Build type: `dockerfile`**, file `Dockerfile` at repo root
+- **Port: `80`**
+
+The Dockerfile is two-stage:
+
+1. `node:22-alpine` — runs `npm ci` and `npm run build` to produce
+   `dist/`
+2. `nginx:1.27-alpine` — copies `dist/` to nginx's web root and serves
+   it (with gzip, security headers, 1-year cache for hashed assets,
+   and a `try_files` fallback for Astro's UTF-8 slugs)
+
+## Why not Gitea Actions?
+
+Gitea Actions does **not** ship with managed runners (unlike GitHub
+Actions' `ubuntu-latest`). Without a self-hosted `act_runner` registered
+with matching labels, any workflow run will fail with
+**"No matching online runner with label: ubuntu-latest"**.
+
+The Gitea Webhook mechanism is built into Gitea itself — no runner
+required. It fires the same events but POSTs to a URL you control,
+which is the simplest possible deploy trigger.
+
+If a real CI step is ever needed (lint, test, build artifact), install
+`act_runner` on a box, register it, and write a workflow using
+`runs-on: self-hosted`. See `act_runner` docs for setup.
+
+## Troubleshooting
+
+### Push happened, but site didn't update
+
+1. Open the webhook row in Settings → Webhooks
+2. Open **Recent Deliveries**
+3. Check the most recent one:
+   - Status 200 → deploy endpoint received it, check EasyPanel logs
+   - Status != 200 → check the response body
+   - **No recent delivery** → webhook is not bound to this branch/event
+     or the push target branch doesn't match the filter
+
+### Build fails inside EasyPanel
+
+1. EasyPanel UI → service `dealplustech-astro` → Logs tab
+2. Look for the `nixpacks` or `docker build` step
+3. Common failures:
+   - **"No start command could be found"**: you're on `nixpacks`. Switch
+     build type to `dockerfile` and point at `Dockerfile` at repo root.
+   - **"Node.js v20.x is not supported by Astro"**: the Dockerfile is
+     using `node:20-alpine`. It should be `node:22-alpine` (Astro 6
+     requires `>=22.12.0`).
+   - **"Failed to sync changes"** (HTTP 500 from the deploy endpoint):
+     usually a panel-side state issue. Retry, or open the service in
+     the panel UI and check container state.
+
+### Want to redeploy without a code change
+
+The webhook URL itself is idempotent. You can hit it directly with:
+
+```bash
+curl -X POST \
+  "http://110.164.146.47:3000/api/deploy/772d2c3a4a7d8671657c947c059bc1cdc64bd816efb7fbe2"
+```
+
+A `200` response with body `Deploying...` means the panel accepted the
+trigger. The actual rebuild happens in the background — check EasyPanel
+UI for the progress.
