Release version 1.1.14 - Restore plugin functionality

**CRITICAL FIX:** Restored plugin to working state after v1.1.8-1.1.13 were completely non-functional.

**Root Cause:**
- v1.1.8 moved class instantiation from individual files to init_classes() method
- v1.1.13 wrapped classes in class_exists() guards
- Combination prevented any classes from being instantiated
- Result: No settings, no frontend, no backend functionality

**Solution:**
- Reverted to v1.1.2 pattern (last working version)
- Each class file now instantiates itself with `new ClassName();`
- Removed init_classes() method and woocommerce_loaded hook
- All class_exists() guards remain for redeclaration protection

**What Now Works:**
✅ WooCommerce Settings → Tier & Package Prices tab
✅ Product edit pages show tier/package pricing meta boxes
✅ Frontend displays pricing tables on product pages
✅ Cart applies tier/package pricing correctly
✅ All plugin functionality fully operational

**Files Modified:**
- includes/class-wc-tpp-admin.php
- includes/class-wc-tpp-product-meta.php
- includes/class-wc-tpp-frontend.php
- includes/class-wc-tpp-cart.php
- wc-tier-and-package-prices.php (removed init_classes)
