Prod prerequisites identified in deep review of the scheduler automation:
- data/sql/122: GRANT SELECT ON rosreestr_deals TO tradein_fdw_reader.
scheduler import reads gendesign.rosreestr_deals via FDW, but the reader
role was REVOKE ALL (100_tradein_fdw_role.sql) with no grant → import
would fail "permission denied for table rosreestr_deals". Single parent
grant suffices for declarative partitioning.
- tradein 072: seed next_run_at = next night-window (tomorrow + window_start
hour, pinned UTC) instead of NULL. NULL made get_due_schedules() fire both
rows within ~1 tick of deploy — outside the night window and (for cian)
before the FDW grant lands. Stays enabled; just shifts first fire to night.
