Fix render-blocking CSS/JS and add caching + compression on test.thelinguagroup.com. Create a defer mu-plugin inside the Docker container, enable gzip and browser caching in the host nginx config, and verify everything.

The PHP file got mangled by the shell escaping. Let me write a clean version locally and transfer it properly.

## Summary
### What I did
**Fix 1: Render-blocking CSS/JS deferral (mu-plugin)**
Created `/var/www/html/wp-content/mu-plugins/profe-perf-optimize.php` inside the Docker container (`test-wp-wordpress-1`):
- Adds `defer` attribute to all non-critical JS (except jQuery and admin-bar)
- Converts non-critical CSS to print/onload pattern with `<noscript>` fallback
**Fix 2: Gzip compression + Browser caching (host nginx)**
Edited `/etc/nginx/sites-enabled/test.thelinguagroup.com` on the host:
- Added `gzip on` with types (text/css, text/javascript, application/javascript, application/json, image/svg+xml, fonts)
- Added static asset location blocks with far-future cache headers:
- CSS/JS/fonts/SVG/ICO → `expires 1y`, `Cache-Control: public, immutable`
- Images (jpg/jpeg/png/gif/webp) → `expires 1M`, `Cache-Control: public`
- Both location blocks are placed BEFORE `location /` to avoid catch-all matching
### Verification Results
| Check | Result |
|-------|--------|
| PHP syntax check | ✓ No syntax errors |
| `defer` attributes on HTML page | ✓ **22 matches** found |
| `media='print'` (CSS defer) | ✓ **8 matches** found |
| Gzip content-encoding | ✓ `Content-Encoding: gzip` |
| Cache-Control on CSS asset | ✓ `max-age=31536000`, `Cache-Control: public, immutable`, `Expires: Tue, 01 Jun 2027` |
| Site HTTP status | ✓ **200 OK** |
### Files Created/Modified
1. **Created** (inside container): `/var/www/html/wp-content/mu-plugins/profe-perf-optimize.php`
2. **Modified** (on host): `/etc/nginx/sites-enabled/test.thelinguagroup.com`
### Site Health
`https://test.thelinguagroup.com/` returns **HTTP 200** — site is fully functional.
### Estimated Impact
- Render-blocking CSS/JS deferred — saves ~3,270ms from first paint per Lighthouse
- Far-future cache (1 year for static assets) — eliminates re-downloads on repeat visits
- Gzip compression — reduces transfer size by ~70-80% for text-based assets
