fix: entrypoint.sh set -e crash, __main__.py PostgreSQL check, cli.py seed placeholders

- entrypoint.sh: use NEEDS_INIT variable instead of exit codes (set -e was killing the script)
- __main__.py: skip db_path.exists() check when using PostgreSQL
- cli.py: use dual-backend placeholders for _seed_context (was using SQLite ? syntax)
- cli.py: use 'admin' instead of 'system' for seed updated_by (FK constraint)
