chore: drop unused dev dependencies and refresh the lockfile

Remove four development dependencies that nothing in the repo uses:

- tox: no tox.ini, no setup.cfg, no [tool.tox] section
- bumpversion: no config either; CONTRIBUTING documents bumping
  __version__.py by hand and the release workflow verifies it
- pytest-csv: no --csv usage in pytest.ini, the Makefile or CI
- pytz: no imports anywhere

pytz stays installed as a transitive dependency of dbt-adapters and
dbt-common, so nothing changes at runtime. Removing the direct
declaration only drops a claim this repo does not use.

Then refresh the rest with `uv lock --upgrade`: 49 packages moved, 2
added and 7 removed. This supersedes three open dependabot PRs, each of
which lands at or below the version resolved here: #808 (cryptography
48.0.0 -> 50.0.1, dependabot asked for 50.0.0), #717 (msgpack 1.1.2 ->
1.2.2, asked for 1.2.1) and #713 (pyjwt 2.12.1 -> 2.13.0).

Development dependencies only. The adapter's runtime requirements in
[project.dependencies] are untouched.

 #### Under the hood
 
 - Replace mypy with [`ty`](https://docs.astral.sh/ty/) for type checking, completing the move to a single Astral toolchain (Ruff for lint and format, `ty` for types). Same scope as before (`dbt/adapters`, unresolvable `dbt.*` imports ignored), configured in `pyproject.toml`. `ty` runs in a new Type check workflow rather than on pre-commit.ci, which blocks the network access it needs. [#712](https://github.com/dbt-msft/dbt-sqlserver/issues/712)
+- Drop four unused development dependencies and refresh the lockfile. `tox` had no `tox.ini` or `[tool.tox]` config, `bumpversion` had no config either (releases bump `__version__.py` by hand, as CONTRIBUTING describes), and `pytest-csv` and `pytz` had no references anywhere. `pytz` stays installed as a transitive dependency of `dbt-adapters` and `dbt-common`, so nothing changes at runtime. `uv lock --upgrade` then refreshed the rest, moving 49 packages and removing 7 in total. Development dependencies only: the adapter's own runtime requirements in `[project.dependencies]` are unchanged.
