feat(cli): add Coding Plan Global/Intl region support

Add support for Coding Plan international region with separate base URL:
- Add CodingPlanRegion enum (CHINA, GLOBAL) for region management
- Add CODING_PLAN_INTL_MODELS template with intl base URL
- Add version storage for both regions (codingPlan.version/versionIntl)
- Update AuthDialog to show both region options
- Update useCodingPlanUpdates to handle region-specific updates
- Add i18n translations for all supported languages
- Fix and update unit tests

Users can now choose between:
- Coding Plan (Bailian, China) - https://coding.dashscope.aliyuncs.com/v1
- Coding Plan (Bailian, Global/Intl) - https://coding-intl.dashscope.aliyuncs.com/v1
