feat: auto-select plugin registry based on timezone

Auto-detect timezone and select the geographically closest plugin
registry for faster plugin downloads.

Changes:
1. Add detectPluginRegistry() function to auto-select registry:
   - Asia/Shanghai & China → Hangzhou mirror
   - Southeast Asia → Singapore mirror
   - Americas → North America mirror
   - Default → Hangzhou mirror

2. Add PLUGIN_REGISTRY to config file generation

3. Update plugin templates to use PLUGIN_REGISTRY variable:
   - scripts/config-template/ai-gateway.sh (ai-proxy, ai-statistics, model-router)
   - scripts/config-template/ai-proxy.sh

4. Support manual override via PLUGIN_REGISTRY environment variable

Available registries:
- higress-registry.cn-hangzhou.cr.aliyuncs.com (default)
- higress-registry.ap-southeast-7.cr.aliyuncs.com (Southeast Asia)
- higress-registry.us-west-1.cr.aliyuncs.com (North America)
