feat(options): show persistent repair issue after currency mode change

Add DATA_STATISTICS_REVIEW_REQUIRED flag to config_entry.data. Set on
currency mode change, cleared on same-mode save. On every async_setup_entry
with flag set, delete and recreate the repair issue so it reappears after
HA restart even if previously dismissed.

Repair issue text explains that HA Recorder shows its own unit-change
dialog (delayed) and recommends deleting old statistic data rather than
re-labeling, which would leave wrong values with the new unit.

Impact: Users are notified to review statistics and automations after
switching between base/subunit currency mode. Notification persists across
HA restarts until acknowledged by saving display settings again.
