Sowlov Speed + Quick Wish Templates Update

Files changed:
- templates/__feeds_comment.form.tpl
  Added login-user quick wish template chips under the wish textarea.
- templates/_head.css.tpl
  Added small CSS for the Sowlov quick wish chips.
- templates/_head.tpl
  Added CDN preconnect/dns-prefetch for faster loading of external theme assets.
- templates/_js_files.tpl
  Loads js/sowlov-wish-speed.js for both logged-in users and guests.
- js/sowlov-wish-speed.js
  Creates 2-3 visible short wish templates based on post text/hashtags and rotates them on reload.
  Also applies light performance helpers to dynamically added images/media.
- .htaccess
  Added Brotli/Deflate compression and ETag cleanup for faster static assets.

Quick wish behavior:
- Logged-in users can tap a template to fill the wish box. Guests can see templates, but tapping them opens the login gate.
- Templates are based on words and hashtags in each celebration, such as birthday, wedding, anniversary, baby, graduation, business, new car/house, God/Allah, etc.
- Uses simple Nigerian-friendly wording like: Congratulations my boss, keep winning; Much love; Queen of the day; More wins; God bless you.
- Shows 2 or 3 suggestions at once. Other matching suggestions can appear when the page reloads.
- Clicking a template fills the wish box for logged-in users. For guests, clicking a template asks them to log in first.

Speed behavior:
- Adds native lazy loading and async image decoding by JavaScript for current and newly loaded posts.
- Changes heavy feed media preload from auto to metadata.
- Adds server compression/cache improvements for theme assets.

After upload:
1. Upload and replace the elengine theme folder.
2. Delete files in /content/themes/elengine/templates_compiled/ except index.html and .htaccess if present.
3. Clear cache from admin panel/browser.
