-- Adds the missing updated_at column + trigger to depreciation_schedules.
-- The previous migration (20260516120000_assets_and_depreciation) seeded the
-- table without it, which violates the project convention requiring every
-- table to have updated_at managed by update_updated_at_column(). Since rows
-- there only mutate twice (insert, then later when the post handler fills
-- in journal_entry_id + posted_at), updated_at lets audits trace the latest
-- state change without joining against journal_entries.created_at.
