- Default TZ=Africa/Nairobi baked into the sidecar image; override via
compose TZ env var if another region is ever needed.
- Rename BACKUP_TIMES_UTC → BACKUP_TIMES (legacy var still honored for
back-compat). Times are now interpreted in the container's local TZ,
so "02:30" means 02:30 EAT, not UTC.
- Log timestamps and dump filenames use %FT%T%z / %Y%m%d_%H%M%S_%Z
(e.g. tracksolid_db_20260424_115729_EAT.sql.gz) so the TZ is visible
on every artifact.
- Prune cutoff computed in local time; YYYYMMDD regex unchanged so it
still matches legacy UTC filenames during the transition.
