feat(app): in-app asset picker (wechat_assets_picker) - unlimited multi-select with range selection

Review fixes: per-asset originFile error isolation (failed asset skipped, not whole batch); drop maxSdkVersion from READ_MEDIA_VISUAL_USER_SELECTED (API 34+, no upper bound); originFile doc accuracy (API 30+ direct path vs Android 10 ScopedCache copy).
