The `select(ImportSettings).where(id == 1)).scalar_one()` singleton load was
repeated 15× across services, API, and 5 task modules. Added async load() +
sync load_sync() classmethods on the model and migrated all 15 full-row sites
(callers already imported ImportSettings, so no new imports; dropped download's
now-orphaned select import). Left maintenance.py's deliberate column-select
(import_scan_path only) as-is.
Rest of the service layer was already adequately DRY — the Record/to_dict
pattern is only 2 instances and the savepoint find-or-create recovery is
correctly per-entity, so neither was forced into a shared abstraction.

Settings GET returns the single-row ImportSettings DB record; PATCH does
selective field updates (only known editable fields are applied; unknown
keys silently ignored). System stats returns image/tag/storage counts,
task status histogram, and the active batch summary in one shot for the
Settings overview tab.
