Hi, I'd like to contribute a fix for this issue (patch attached).

Root cause: for command runs (backup-db, restore-db, check-data-version, ...), Bootstrap.configureLogging() in commons-bootstrap sets the file log pattern to %-5level - %msg%n, which lacks %date - while server mode uses %date %-5level [%thread] %logger{36} %msg%n. Hence command log files have no dates.

Fix: add a static helper in CommandHandler that prepends %date to the FILE appender's pattern. It is a no-op in server mode (Bootstrap.command == null guard) and idempotent (skips if the pattern already contains %d, so it won't double-prepend if commons is fixed upstream later). It is called from the CommandHandler constructor (covers backup-db, restore-db, check-data-version, clean-db, reset-admin-password, apply-db-constraints, translate) and from a new Upgrade constructor, since Upgrade extends AbstractPlugin directly (covers upgrade.log). Console output is left unchanged.

Verified with a minimal repro replaying the command-mode logging config: before - INFO - ...; after - 2026-07-10 13:42:29,714 INFO - ....
