🐛 fix: shutdown countdown ignores mode change, timer leaks

Browse Source 
Critical: handleShutdownAfterFinish() captured shutdown mode in a
closure at scheduling time — changing mode during countdown was ignored,
causing unexpected system shutdown/restart/sleep.

Now reads shutdownMode at execution time, clears timer when mode
changes to 'nothing', clears orphaned timers before creating new ones,
and adds error handling on exec() calls.

Also: guard stats timer against double-start in upload-manager.
