style: exclude vendor/ from black/isort and reformat our sources

CI lint failed because `black --check app rosemary core` walks into the
`app/modules/generator/vendor/` tree we don't own. Added `extend-exclude`
for `vendor/`, `node_modules/` and `migrations/` to both black and isort
in pyproject.toml (flake8 was already excluded in the previous commit).

Ran `black` + `isort` on the files we do own — routes.py and the four
new generator test modules — so the CI `--check-only` pass is clean.

No behaviour changes.
