* Decodes [MeshLogPrefs.retentionDays], which overloads two sentinels onto the day count: [KEEP_FOREVER] never prunes

* and [ONE_HOUR] keeps only the last hour.

*

* Both sentinels are real user selections rather than "unset", so pruning callers must resolve the window here instead

* of treating the setting as a plain day count.
