refactor: 中间层消除硬编码波段号+CRS动态探测

- GlintRemovalStep/handler/service 全部改为传递波长参数而非波段索引
- ContentMapper 移除 EPSG:32651 硬编码, 新增 _ensure_crs() + _probe_crs_from_file()
- _prepare_shared_context 在 read_csv_data 前先探测边界文件 CRS
- GUI QSpinBox→QDoubleSpinBox，默认值改为波长(nm)，placeholder 提示自动探测
- 消除 38/36/49/47/25/37/65/91 等所有魔法数字
