fix(python-uv): pass –no-default-groups to uv export (#869)

PEP 735 dependency-groups.dev is included by default in uv export, so dev/test deps (moto, pytest, cryptography, docker, …) currently land in every Lambda zip — ~67MB of bloat per function. Adding –no-default-groups mirrors the prior pip-tools behavior (extras/dev not auto-shipped) and cuts cold install time ~4-5x.
