feat(settings): unify backgrounds and menu card controls

[qiin2333]

改了啥呀

• 设置页背景改为复用主页当前的 BackgroundSource.ResolvedTarget，主页、设置页和保存原图共享同一目标与 UUID 缓存键。
• 背景刷新时显式失效当前解析结果；保存原图只读取当前缓存，不再偷偷重新请求随机图接口。
• 删除只为保存图片服务的额外 LruCache，PNG 编码移到 IO 线程，减少大图内存占用和主线程卡顿。
• 在常规设置页增加“游戏菜单卡片”入口，并抽出 GameMenuCardVisibilityEditor 供设置页和串流内菜单共同使用。

为啥要改

随机图片 API 对同一个 URL 的多次请求可能返回不同图片。原先主页、设置页、下载链路各自请求，导致设置背景或保存结果偶尔和主页不一样——这种会分身的杂鱼缓存状态该收拾掉啦。

另外，游戏菜单的卡片展示配置只藏在串流中的菜单里，不容易发现。现在可以在进入串流前直接配置，同时仍保留串流内即时调整。

用户影响

• 设置页与主页始终使用同一张背景图，仅保留各自的蒙层差异。
• 长按保存得到当前主页对应的未加滤镜原图，不会抽到下一张随机图。
• 用户可以从设置页选择码率、音频与震动、陀螺仪、快捷键卡片；至少保留一张卡片。

验证

• git diff --check
• .\gradlew.bat :app:compileNonRootDebugKotlin :app:assembleNonRootDebug
• 魅族 17 真机覆盖安装 app-nonRoot-debug.apk
• 真机验证主页与设置页背景构图一致
• 真机长按保存并对照 PNG，确认与当前主页原图一致
• 检查 AndroidRuntime logcat，无崩溃

📝 Walkthrough

Walkthrough

The change replaces in-memory wallpaper caching with resolved-target Glide disk caching. It also adds a shared editor for game-menu card visibility and exposes the selector in Android settings with localized summaries.

Changes

Wallpaper caching

Layer / File(s)	Summary
Resolved wallpaper target caching app/src/main/java/com/limelight/preferences/BackgroundSource.kt	BackgroundSource caches resolved targets by source and orientation, generates cache keys, and invalidates cached resolutions when the active source changes.
Glide wallpaper loading app/src/main/java/com/limelight/PcView.kt, app/src/main/java/com/limelight/preferences/StreamSettings.kt	Wallpaper requests use resolved cache keys, support local files and remote candidates, and cancel raw Glide FutureTarget instances.
Disk-cache wallpaper saving app/src/main/java/com/limelight/PcView.kt	Wallpaper saving reads only from Glide disk cache and reports directory or bitmap encoding errors.

Game-menu card visibility

Layer / File(s)	Summary
Shared card visibility editor app/src/main/java/com/limelight/gamemenu/GameMenuCardVisibilityEditor.kt	The shared editor presents four selectable cards, persists confirmed selections, and returns localized selected labels.
Game-menu settings integration app/src/main/java/com/limelight/gamemenu/GameMenu.kt, app/src/main/java/com/limelight/preferences/GameMenuCardsPreference.kt, app/src/main/res/xml/preferences.xml, app/src/main/res/values*/strings.xml	GameMenu and Android preferences use the shared editor and display localized selection summaries.

In `@app/src/main/java/com/limelight/preferences/BackgroundSource.kt`:
- Around line 131-150: Update the legacy URL handling in StreamSettings around
the migration/load flow to persist through BackgroundSource.KEY_API_URL rather
than writing legacy keys directly. For a nonblank URL, call
setActivePreservingExtras with BackgroundSource.Api; for a blank URL, call
setActive with BackgroundSource.Auto, ensuring KEY_SOURCE and resolved-target
cache state are updated.
