- Add truenas_migrate/csv_source.py: parses SMB and NFS share definitions
from customer-supplied CSV files; returns same dict shape as parse_archive()
so migrate.py is untouched
- Add smb_shares_template.csv and nfs_shares_template.csv with annotated
headers and example rows (# comment rows are skipped by the parser)
- Update cli.py: interactive wizard gains a source-type step (archive vs CSV);
run() resolves CSV source via --smb-csv / --nfs-csv args; --debug-tar is now
optional; argparse validates mutual exclusion of archive and CSV flags
