fix(camera): prefer DConfig resolution over local config (BUG-366203)

When preferredResolution is set via DConfig, use it directly instead
of the locally cached resolution from config file on first launch.

DConfig的preferredResolution配置优先于本地配置文件中的分辨率，
修复首次打开应用时仍使用本地旧配置的问题。

Log: 修复preferredResolution首次启动不生效的问题
PMS: BUG-366203
Influence: 设置preferredResolution后首次启动即可生效，无需重启两次。
