   * 初始化歌词加载与展示逻辑

   * @param isToast 是否弹出Toast提示（可选）获取在线歌词为true
   * @param isApi2 是否使用API2获取歌词（可选）
   *
   * 主要流程：
   * 1. 设置歌词显示样式（字号、颜色、行距、对齐、动画等）。
   * 2. 优先尝试本地读取歌词文件（支持加密和普通两种后缀）。
   * 3. 若本地无歌词且满足条件（调试模式或会员且安装时间超过2天），则联网获取歌词。
   * 4. 获取到歌词后，解析并设置到lyricController，并保存到本地。
   * 5. 本地有歌词时，读取文件内容（自动检测编码，支持解密），解析后设置到lyricController。
   * 6. 解析失败或读取失败时，清空歌词显示。
   *
   * 注意事项：
   * - 仅会员且安装时间超过2天才可联网获取歌词（调试模式isDebug=true时跳过限制）。
   * - 支持加密歌词文件（.lrcc），自动检测并解密。
   * - 歌词内容解析后通过lyricController驱动UI渲染。
