Refactor IP region lookup to use external API

Replaced the local ip2region database and related PHP classes with an external API (ip.asbid.cn) for IP region lookup in functions.php. Removed the entire ip2region directory and its dependencies, simplifying maintenance and reducing local storage requirements. Updated caching logic to store API results for one month. Also updated the theme version in index.php to 1.1.
