fix: prevent dockHiddenSurfaceIds from being reset to empty

The commit refactors the save logic for tray sort order data to prevent
`dockHiddenSurfaceIds` from being accidentally cleared. Previously,
`onAvailableSurfacesChanged()` called `saveDataToDConfig()` which
saved all configuration values, including `dockHiddenSurfaceIds`, at a
point where other processes might be concurrently modifying this value,
leading to a race condition where it could be overwritten with empty
data.

The fix splits the monolithic `saveDataToDConfig()` into targeted
save methods: `saveSortOrderToDConfig()`, `saveHiddenIdsToDConfig()`,
`saveDockHiddenIdsToDConfig()`, and `saveCollapsedToDConfig()`. In
`onAvailableSurfacesChanged()`, only sort order and hidden IDs are
saved, deliberately excluding `dockHiddenSurfaceIds` to avoid the
race condition. The `dockHiddenSurfaceIds` is now only saved from
`setDockVisible()` via the new `saveDockHiddenIdsToDConfig()` method,
when the value is explicitly changed.

Influence:
1. Test tray plugin visibility toggling and verify
`dockHiddenSurfaceIds` persists correctly
2. Verify `hiddenSurfaceIds` and sort order still update properly on
surface changes
3. Test scenarios where multiple processes might modify dock
configuration simultaneously
4. Verify no data loss occurs when hiding/showing dock tray items
5. Test that collapsed state saves and loads correctly

fix: 修复 dockHiddenSurfaceIds 被意外重置为空的问题

本次重构了托盘排序数据的保存逻辑，防止 `dockHiddenSurfaceIds` 被意外清
空。之前 `onAvailableSurfacesChanged()` 调用 `saveDataToDConfig()` 会保
存所有配置值，包括 `dockHiddenSurfaceIds`，而此时其他进程可能正在并发修
改该值，导致竞态条件，使其被空数据覆盖。

修复方案将单一的 `saveDataToDConfig()` 拆分为针对性的保存方
法：`saveSortOrderToDConfig()`、`saveHiddenIdsToDConfig()`、
`saveDockHiddenIdsToDConfig()` 和 `saveCollapsedToDConfig()`。
在 `onAvailableSurfacesChanged()` 中，只保存排序和隐藏 ID，刻意排
除 `dockHiddenSurfaceIds` 以避免竞态条件。`dockHiddenSurfaceIds`
现在仅在通过 `setDockVisible()` 显式修改时，通过新增的
`saveDockHiddenIdsToDConfig()` 方法保存。

Influence:
1. 测试托盘插件的可见性切换，验证 `dockHiddenSurfaceIds` 是否持久化保存
2. 验证在 surface 变化时 `hiddenSurfaceIds` 和排序是否正常更新
3. 测试多个进程同时修改 dock 配置的场景
4. 验证显示/隐藏 dock 托盘项时数据不会丢失
5. 测试折叠状态的保存和加载是否正常
