fix: Customer SPA loading and optimize production build size

Problem 1: Customer SPA not loading (stuck on 'Loading...')
Root Cause: Missing type='module' attribute on customer SPA script tag
Solution: Added script_loader_tag filter to inject type='module' for ES modules

Problem 2: Production zip too large (21-41MB)
Root Cause: Build script included unnecessary files (dist folder, fonts, .vite, test files, archives)
Solution:
- Exclude entire customer-spa and admin-spa directories from rsync
- Manually copy only app.js and app.css for both SPAs
- Exclude dist/, archive/, test-*.php, check-*.php files
- Simplified Frontend/Assets.php to always load app.js/app.css directly (no manifest needed)

Changes:
- includes/Frontend/Assets.php:
  * Added type='module' to customer SPA script (both manifest and fallback paths)
  * Removed manifest logic, always load app.js and app.css directly
- build-production.sh:
  * Exclude customer-spa and admin-spa directories completely
  * Manually copy only dist/app.js and dist/app.css
  * Exclude dist/, archive/, test files

Result:
✅ Customer SPA loads with type='module' support
✅ Production zip reduced from 21-41MB to 1.6MB
✅ Only essential files included (app.js + app.css for both SPAs)
✅ Clean production package without dev artifacts

Package contents:
- Customer SPA: 480K (app.js) + 52K (app.css) = 532K
- Admin SPA: 2.6M (app.js) + 76K (app.css) = 2.7M
- PHP Backend: ~500K
- Total: 1.6M (compressed)
