The UPDATE and CREATE all-day branches each called getHouseholdTimezone(db)
independently, so a drain processing both an all-day create row and an
all-day update row issued two identical app_config SELECTs. Add a lazy
per-cycle TimezoneResolver (mirroring the existing clientCache thread-through)
created in runOutboxDrain and passed into dispatchRow. The read stays lazy —
cycles with no all-day work never touch the DB — but is shared across all
all-day rows in a cycle. Behavior unchanged.
