Fix Settings.php class loading timing issue (v1.1.2)

CRITICAL BUG FIX: v1.1.1 still had the same error!

Root cause analysis:
- v1.1.1 changed hook to woocommerce_init but error persisted
- Real issue: Settings.php was require_once'd in Plugin::includes()
- At that point, class extends WC_Settings_Page which doesn't exist yet
- Even woocommerce_init fires before WC_Settings_Page is loaded

Solution:
- Removed require_once from Plugin::includes() (line 93)
- Moved require_once to Plugin::add_settings_page() (line 196)
- Settings.php now loads on-demand via woocommerce_get_settings_pages filter
- This filter fires when WooCommerce has loaded all settings classes

Changes:
- includes/Plugin.php: Delayed Settings.php inclusion with explanatory comment
- wc-composable-product.php: Version bump to 1.1.2
- CHANGELOG.md: Documented fix and noted v1.1.1 was insufficient

This addresses the actual root cause that persisted through 3 versions.

+## [1.1.2] - 2024-12-31
+
+### Fixed
+
+- **CRITICAL**: Fixed persistent "Class WC_Settings_Page not found" error that continued in v1.1.1
+- Root cause: Settings.php was being included too early (during plugin init) before WC_Settings_Page was loaded
+- Solution: Delayed Settings.php inclusion until `woocommerce_get_settings_pages` filter when class is guaranteed to exist
+
+### Technical
+
+- Removed `require_once Settings.php` from `Plugin::includes()` (line 93)
+- Added `require_once Settings.php` to `Plugin::add_settings_page()` (line 196)
+- Settings file now loads on-demand when WooCommerce requests settings pages
+- Previous hook change (woocommerce_init) was insufficient - class loading order was the real issue
+
+### Notes
+
+- v1.1.1 attempted to fix this with hook change but the error persisted
+- This version addresses the actual root cause: premature class extension
+
