Fix Baserow migrations and LobeHub copy

Set PYTHONPATH and run manage.py migrate for Baserow so backend, premium, and enterprise source packages are discovered during migrations. In the LobeHub installer, copy all files from scripts/migrateServerDB into the .next/standalone directory (instead of only docker.cjs) so required migration and helper files are included.
