build: release version 4.4.8-ba7opf.4 (557)

工作网格 QSO 详情弹窗里，中间那一列（通联行的「n QSO」、标记行的「标记」）
原来和左右两列一样占 weight(1f)（各 1/3 宽），而该列文字是居中的，字样两侧的
空白被白白占用。现改为按内容宽度占位（去掉 weight(1f)），左右两列仍各占
weight(1f)：两外列等分剩余宽度 ⇒ 中列起点正好落在原居中字样的左边界，
因此

- 「n QSO」「标记」字形位置与之前逐像素一致，日期与展开箭头（右对齐）不动；
- 省出的中列左半空白全部交给呼号列，呼号列宽度由 W/3 增至 (W - 字样宽)/2，
  411dp 屏约 +33dp，长呼号（含 /P、活动特别呼号）多显示约 3 个字符，
  并可一直排到「n QSO」字样左侧才省略。

仅影响地图页「网格通联详情」弹窗内的两类行；设置页日志本行本就是
「呼号 weight + 尾部标签 wrap-content」，口径已一致，未改动。
