Release version 1.1.11 - Complete redeclaration protection

Fixed critical constant redeclaration warnings/errors for all plugin
constants affecting versions 1.1.3-1.1.10. This completes comprehensive
protection against all redeclaration issues by protecting constants.

Fixes:
- Constant redeclaration warnings/errors for WC_TPP_VERSION, WC_TPP_PLUGIN_DIR, WC_TPP_PLUGIN_URL, WC_TPP_PLUGIN_BASENAME
- Potential errors when plugin constants already defined
- Plugin initialization failures caused by constant redeclaration

Technical Changes:
- Wrapped all define() calls in defined() checks
- Protected WC_TPP_VERSION, WC_TPP_PLUGIN_DIR, WC_TPP_PLUGIN_URL, WC_TPP_PLUGIN_BASENAME
- Prevents warnings/errors during WordPress plugin activation/deactivation cycles
- Comprehensive protection: all global functions and constants now safely guarded
- No more redeclaration issues possible

Updated Files:
- wc-tier-and-package-prices.php (version 1.1.11, all constants protected)
- composer.json (version 1.1.11)
- CHANGELOG.md (v1.1.11 section)
- All translation files compiled (.mo files)
