feat(backup): "keep every backup" option — timestamped files per exit

Sub-option of "back up on every exit": when on, backup.Run/RunADIF stamp the
filename with the time (opslog-YYYY-MM-DD-HHMMSS.db) so each run is a distinct
file instead of overwriting the day's snapshot. Rotation still trims to the
newest N (raise Rotation for a longer history). Threaded as a `unique` flag
through runConfiguredBackup/backupLogADIF from BackupSettings.KeepAll
(keyBackupKeepAll); UI sub-checkbox shown only when EveryExit is on.
