--port without a value (or with a --flag value) previously silently
fell back to all-ports mode because process.argv[indexOf+1] was
undefined. Now exits 1 with an explicit error. Hardens the script
before it gets wired into deploy in Task 17.

Idempotent one-time backfill that runs as part of the deploy:
1. Ensures Clients/Companies/Yachts roots per port.
2. Copies entity FKs from completed workflows onto signed file rows
(legacy completions ran before the auto-deposit handler shipped).
3. Ensures per-entity subfolders for every entity with attached
files and sets files.folder_id.
pg_advisory_xact_lock(hashtext(portId)::bigint) per port so concurrent
runs serialize. Safe to re-run; the SELECT-then-UPDATE pattern targets
only rows where folder_id IS NULL.
