- A group in a backup from before version 23 has no rolling code, and a
restore wrote 0 to NVS for it. It keeps the code NVS has.
- A restore reads each record into one that starts as the shade, group
or settings it replaces, so what an older version lacks stays as it
was (the update check below version 20 among them), as before.
- restoreFile and loadFile read the rooms, shades and groups through one
readModel(); the settings, network and radio are applied by helpers.
- The shade's tilt is forgotten where the shades are written, not in the
conversion to a record.
- rollingCodeAfterLoad moves to RollingCode.h and its tests to
test_rollingcode.
- The topics a deleted shade or group clears are one list each
(MqttTopics.h), tested against what is published.
- e2e: a restore of the shades brings back every shade and group, and
the README has the rollback check by hand.
