Replace the single BACKUP_HOUR/BACKUP_MINUTE slot with a comma-separated
list of UTC times. Scheduler walks all slots and sleeps until the soonest
future one, so four daily backups become a one-line env change:
BACKUP_TIMES_UTC=02:30,08:30,14:30,20:30 (default)
Legacy BACKUP_HOUR/BACKUP_MINUTE still honored as a single slot for
backwards compatibility with existing .env files.

Adds a `db_backup` sidecar that dumps tracksolid_db every night at
02:30 UTC (configurable via BACKUP_HOUR/BACKUP_MINUTE), gzips the
output, and uploads to s3://fleet-db/daily/<dbname>_<ts>.sql.gz on
the rustfs S3-compatible instance (s3.rahamafresh.com). Prunes
objects older than BACKUP_KEEP_DAYS (default 30).
Required .env additions (Coolify UI):
RUSTFS_ENDPOINT=https://s3.rahamafresh.com
RUSTFS_ACCESS_KEY=...
RUSTFS_SECRET_KEY=...
RUSTFS_BUCKET=fleet-db
Mitigates data loss when Coolify service recreation wipes the
service-ID-scoped timescale-data volume.
