轨迹能导出，跟随有三态，横屏不再缺东西

• 历史轨迹可以导出成 GPX：今天、最近 7 天、30 天、1 年，或者自己挑一段起止时间。导出的
  文件落在系统的「下载」目录里，导完可以直接分享出去，用别的软件打开就是一条条带时间的
  轨迹点。挑的那段时间里没有轨迹的天会整条跳过，不写进文件。
• 地图右侧的「跟随」改成三态：关、锁定中心·正北朝上、锁定中心·航向朝上。要正北还是跟着
  车头转，点一下就能换，不用进设置。
• 台站页横屏下，排序入口不再跟着统计行一起消失。按哪个字段排也会记住，下次打开还是上次
  选的那个，跟着备份一起走。
• 自动上报那条横条开「详细档」时，最左边会显示这一发真正要发出去的信标符号。智能档按
  速度换符号、纯网络定位单独指定的那一枚，都会跟着变，看到的就是地图上会出现的那个图标。
• 启动时体检一次权限，只说「本来有、现在被关掉」的那几项，不去念一遍你从来没给过的权限。
  定位权限被系统关掉时，前台服务声明失败也不会再把进程带走。
• 横屏下地图画的那几层（轨迹、信标点、精度圈、热力图）不再画到左侧卡片和底部横条底下。
  以前它们铺满整屏，卡片是磨砂的，蓝线就从卡片里透出来，看着像轨迹压住了卡片。

[2.1.6] - 2026-10-16 (English)

Export the track, pick how the map follows, and landscape stops missing pieces

• History can be exported as GPX: today, the last 7 days, 30 days, a year, or a range you
  pick. The file lands in the system Downloads folder and can be shared straight away; any other
  app that opens it gets the track as timestamped points. Days with no track inside the chosen
  range are skipped whole.
• The map's follow button has three states: off, locked centre with north up, and locked
  centre with heading up. One tap switches between north and heading, no trip to settings.
• On the stations page the sort entry no longer disappears with the statistics row in landscape,
  and the sort field is remembered across launches, travelling with the backup.
• With the reporting bar in detailed mode, the leftmost item is the APRS symbol this beacon will
  actually send. Smart tiers change the symbol by speed and a network-only fix can have its own,
  so what you see is the icon that shows up on the map.
• Permissions are checked once at startup, naming only the ones that were there before and are
  now off, never reciting permissions you never granted. A location permission switched off by the
  system no longer takes the process down when the foreground service fails to start.
• In landscape the drawn layers (track, beacon marks, accuracy ring, heat map) no longer paint
  under the left card or the bottom bar. They used to fill the whole screen, and since the cards
  are frosted the blue line showed through them, looking like the track was on top of the card.
