Pruned per project convention "no unnecessary code comments":
- module docstring: 23 lines → 1 line (the file name + symbol already
state intent; full incident write-up belongs in the commit log)
- wipe_database_entries docstring: 11 lines → 2 lines
- six inline rationale comments in tests/__main__ removed (test
names already encode the intent)

Matrix-deploy variant transitions wipe a consumer's compose stack and
its named DB volume (`compose down -v` in
scripts/container/purge/entity/compose.sh) but `databases.csv` at
$FILE_DATABASE_SECRETS survives the purge. When the next round drops
the consumer from its inventory, the stale baudolo-seed row remains
behind. The subsequent backup run reads that row, attempts
`mariadb-dump -u<entity> -p<old_pw>` against the freshly initialised
RDBMS user that no longer exists, and the systemd unit fails with
"Access denied for user 'matomo'@'127.0.0.1' (using password: YES)"
(job 77797356000 on run 26428080957: matomo dump in
svc-bkp-container-2-local variant 1, where round 1 seeded matomo but
round 2 only deploys postgres + mariadb + svc-bkp itself).
Add `utils.cleanup.databases_csv` mirroring the existing
`utils.cleanup.tokens` pattern: parse the baudolo-seed CSV format
(';'-separated, four columns instance/database/username/password, with
header — verified against baudolo.seed.__main__:check_and_add_entry)
and strip every row whose `database` or `username` column matches an
entity derived from the supplied app ids via
utils.roles.entity_name.get_entity_name. Header and blank lines are
preserved verbatim; the file is rewritten only when at least one row
was removed.
Wire the helper into scripts/container/purge/apps.sh right after the
token-store wipe so every matrix-deploy inter-round purge invokes it
alongside the other cleanups. Operator-triggered purges
(`INFINITO_APPS=<app> bash scripts/container/purge/apps.sh`) also get
the cleanup — that is a behaviour change relative to before, where
the row would survive an operator-triggered entity teardown.
Coverage: 12 unit tests in tests/unit/utils/cleanup/test_databases_csv.py
covering the happy path, the multi-app case, the
`database='*'`/username-match case, the unknown-app no-op, header and
blank-line preservation, the all-rows-removed case, malformed short
rows, and the legacy-header-less file. `make test` green across all 5
targets.
