-- commit_journal_entry: fall back to the draft entry's user_id when
-- auth.uid() is NULL.
--
-- Context: when this RPC is invoked via the service role (one-off repair
-- scripts, cron jobs, internal maintenance flows), auth.uid() returns NULL.
-- The INSERT into voucher_sequences then fails its user_id NOT NULL check
-- *before* ON CONFLICT can resolve to DO UPDATE (PostgreSQL evaluates NOT
-- NULL on the candidate tuple ahead of conflict arbitration). That made it
-- impossible to commit journal entries from any non-interactive context.
--
-- Fix: read user_id from the draft journal entry (which is always set by
-- createJournalEntry) and use it as the fallback attribution on the
-- voucher sequence row. Normal interactive flows still record auth.uid();
-- only the service-role path changes.
