Mechanical, whole-tree `ruff format` pass — no behaviour change. Recorded in .git-blame-ignore-revs (next commit) so git blame skips it.

"""Fold the maintenance re-validation batch from app_state into sysconfig (B-core-11)
|
|
|
|
The admin-tunable `maintenance_revalidate_batch` lived in its own `app_state` column with a
|
|
hand-rolled override-or-default reader in `app.state`, duplicating the sysconfig SPECS pattern. It's
|
|
now a sysconfig key (`system_config` store), so every admin knob lives in one place. This migration
|
|
carries any existing override into the sysconfig store, then drops the dead column. Reversible.
