chore: bump version to 1.1.4

+# 最近照片入口验证
+
+2026-09-08，JDK 17，KIOSK_1080x1920（1080×1920，280dpi，Android 17）。
+
+- Debug 构建通过；24 项 JVM 单元测试通过，其中新增 6 项。
+- `RecentPhotosFlowTest` 的 3 项模拟器测试全部通过。
+- 页面验证覆盖：仅失败时显示入口、点击进入 recent 模式、阻止重复跳转、保持首页返回栈、旧 results 路由默认使用 face 模式。
+- 模拟响应覆盖：空结果、403 后重试、有效照片按服务端顺序展示、无缩略图地址的照片过滤、预览、单选/全选、计价、获取模拟支付链接以及支付成功后的打印导航参数。
+- JVM 测试另外覆盖 URL/SN 编码、GET/Bearer、不发送查询参数、401/403/网络失败、重复请求防护、页面作用域取消。
+- 所有照片和订单 HTTP 请求均被测试拦截器替换为模拟响应；只校验打印导航，不打开打印页面、不创建真实订单、不连接打印机。未进行真实后端端到端联调。
+- 页面测试临时使用 example.test 和测试 Token，结束时恢复原照片盒配置。测试通过已有 Hilt 单例 Provider 获取 WebSocket 依赖而不启动主页面，未建立测试 WebSocket 连接。
+- Espresso 测试依赖升级至 3.7.0，解决旧版本在 Android 17 上调用已移除 InputManager 方法的问题；应用运行依赖不受影响。
+
+## 截图
+
+- [失败页按钮](failure-button.png)：状态由测试设置，相机区域是测试时的黑色画面；按钮位于卡片与倒计时之间，底部布局保持原位置。
+- [最近照片结果页](results.png)：蓝色图片为本地测试素材，价格及支付数据为模拟数据。
+
+## 复现
+
+使用 JDK 17，通过 Gradle 执行：
+
+```text
+:app:assembleDebug :app:testDebugUnitTest
+:app:connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=com.yzx.kiosk.ui.face.RecentPhotosFlowTest
+```
+
+仅在测试模拟器上运行 instrumentation 测试。截图保存在目标应用 external files 目录；手动执行 `am instrument` 后可取回，Gradle 托管测试可能在结束时卸载测试应用并清理截图。
+
+## 最近照片入口语音修正（2026-09-08）
+
+- 新资源：`app/src/main/res/raw/recent_photos_result_page.wav`。
+- 从原成功语音的 2.160 秒处裁切。此处位于开场结束后的静音区间（约 1.634–2.289 秒），保留约 129 毫秒的起始停顿，后续音频样本完全不变。
+- 新音频长 8.890667 秒，48 kHz、16 位 PCM、双声道 WAV。原文件 SHA-256 保持为 `c9146f08eaa02bacac0cc8b574ccad829ae4457e22c3b553f2fd3ad8111b7dc1`。
+- 使用本地 Whisper 转写交叉核对前后内容：新文件从选片提示开始，没有“太棒啦，识别成功啦”开场；后续放大预览、支付按钮和打印提示均保留。模型转写存在个别同音字误差，裁切边界同时通过静音检测和 PCM 样本比对确认。未上传音频。
+- `LocalAudioPlayService` 根据路由 `source=recent` 选择新资源；face、旧入口及其他页面保留原映射。不新增播放触发点。
+- 最终 Debug 构建与 27 项 JVM 单元测试通过；`LocalAudioPlaybackTest` 在 KIOSK_1080x1920 上通过，验证新旧入口资源选择、实际进入播放状态及重复调用不重置媒体项。
+
+## 正常识别结果页增加浏览入口（2026-09-08）
+
+- 在全选行右侧增加「浏览全部照片 ›」文字按钮，16sp、蓝色、无背景/边框，点击区域至少 48dp。全选与浏览是独立点击区域。
+- 仅普通识别结果页显示，recent 页面隐藏。导航采用普通 push（不使用 singleTop/popUpTo），让相同 destination 的两次入栈拥有独立 ViewModel。
+- 原识别结果只初始化一次，避免返回时重新初始化照片尺寸、加载状态和价格；网格继续使用 Compose 自带的可保存滚动状态。
+- 按钮在导航期间阻止连续点击，回到原页时恢复可点击。
+- 最终 Debug 构建、27 项 JVM 单元测试通过；模拟器上 4 项 RecentPhotosFlowTest 和 1 项 LocalAudioPlaybackTest 全部通过。
+- 新测试验证：双击只 push 一次、新旧页面 VM 和选择独立、返回保留原 entry/选择/金额/滚动位置且不重复计价初始化、返回后可再次打开新页、recent 隐藏按钮及每次新入栈重新加载。
+- 计价使用按选择数量计算的模拟响应，无真实订单和打印操作。
+- [实际布局截图](result-toolbar-button.png) 使用 30 张蓝色测试图片展示工具栏位置和长列表场景。
