Usage: ./scripts/test_provider.sh [--no-ui] /path/to/provider.gtpack [bundle-dir]

Creates a temporary Greentic bundle, adds the local provider .gtpack, and
runs setup directly against that bundle. By default this launches the setup
GUI; pass --no-ui to run the non-UI setup flow.

Environment:
  GREENTIC_SETUP_BIN=/path/to/greentic-setup
  USE_TARGET_BIN=1
  TENANT=demo
  TEAM=default
  ENV=dev
