fix: improve Docker clone reliability and log display

- Use bash with pipefail instead of sh to detect pg_dump failures in pipes
- Switch full clone from binary format (pg_dump -Fc | pg_restore) to plain
  text (pg_dump | psql) for reliable transfer through docker exec
- Add --no-owner --no-acl flags to avoid errors from missing roles
- Extract shared run_pipe_cmd helper with proper error handling
- Remove shell commands from progress events to prevent credential leaks
- Fix process log layout overflow with break-all and block-level details
