修复 wx-java-open-multi-spring-boot-starter 中硬编码 HttpClient4 导致的启动失败问题

- 在 WxOpenMultiProperties.ConfigStorage 中新增 HttpClientType 枚举（APACHE_HTTP / HTTP_COMPONENTS）及 httpClientType 字段，默认值为 HTTP_COMPONENTS
- 修改 AbstractWxOpenConfiguration.wxOpenService() 根据 httpClientType 选择对应的 WxOpenServiceApacheHttpClientImpl 或 WxOpenServiceHttpComponentsImpl
- 修改 AbstractWxOpenConfiguration.configHttp() 仅在 httpClientType 为 APACHE_HTTP 时配置 DefaultApacheHttpClientBuilder，消除对 HttpClient4 的强制依赖

Closes #4059
