Release version 1.1.7 - Enhanced user experience features

Added three new customer-facing features to improve product page interaction
and tier pricing functionality.

Features:

Enhanced User Experience:

- Add to Cart button shows disabled state with reduced opacity
- Tier labels display below quantity in italic gray text

Technical Changes:
- Added optional 'label' field to tier pricing admin meta box
- Updated tier save logic to include label field (sanitized)
- Enhanced tier pricing frontend template to display labels
- Added click handler for tier pricing rows in frontend.js
- Added updateAddToCartButton() function to manage button state
- CSS: .wc-tpp-tier-label styling for tier labels
- CSS: Clickable cursor and hover transform for tier rows
- CSS: Disabled button styling (.single_add_to_cart_button:disabled)
