Refactor(Admin): Implement Settings API & AJAX save for Settings Manager

- Refactored WPALLSTARS_Settings_Manager to use WordPress Settings API.
- Stores settings in single 'wpallstars_options' array.
- Implemented robust AJAX saving for specific settings (e.g., color scheme, auto-upload) via WPALLSTARS_Admin_Manager::update_option.
- Updated JS and setting render functions for AJAX.
- Corrected admin menu registration and script enqueue hooks.
- Includes file renames from wp-allstars to wpallstars.
