feat(proxy): add full URL mode and refactor endpoint rewriting (#1561)

* feat(proxy): add full URL mode and refactor endpoint rewriting

- Add `isFullUrl` provider meta to treat base_url as complete API endpoint
- Remove hardcoded `?beta=true` from Claude adapter, pass through from client
- Refactor forwarder endpoint rewriting with proper query string handling
- Block provider switching when proxy is required but not running
- Add full URL toggle UI in endpoint field with i18n (zh/en/ja)

* refactor(proxy): remove beta query handling

* fix(proxy): strip beta query when rewriting Claude endpoints

* feat(codex): complete full URL support

* refactor(ui): refine full URL endpoint hint
