Stefan Agner ed91b18c4b tests: enable flake8-pytest-style (PT) ruff rules (#6857)
* tests: enable flake8-pytest-style (PT) ruff rules

Enable the `PT` ruff rule set and fix the resulting violations across the
test suite:

- PT006: pass parametrize argument names as tuples instead of a single
  comma-separated string.
- PT022: switch fixtures that have no teardown from `yield` to `return`
  so the lack of cleanup is obvious at a glance.
- PT011: add `match=` to broad `pytest.raises(ValueError)` blocks so the
  expected error is anchored to a specific message.
- PT012: hoist setup (patches, branching) out of `pytest.raises()`
  blocks so only the call that is expected to raise remains inside.
- PT013: replace `from pytest import X` with `import pytest` and access
  attributes via the module.
- PT015: replace `try/except` + `assert False` patterns with
  `pytest.raises(...)`.
- PT017: replace `assert` on exceptions inside `except` blocks with
  `pytest.raises(...) as exc_info` and assert on `exc_info.value`.

No behavioral changes to the tests; the full suite still passes.

* tests: address review feedback on PT ruff rule enablement

- Fix fixture return-type annotations after switching `yield` to `return`
  in tests/conftest.py: drop the `Generator[...]`/`AsyncGenerator[...]`
  wrapper for `dns_manager_service`, `supervisor_internet`, `websession`,
  and `mock_update_data` so the annotation matches what the fixture
  actually returns.
- Correct the return-type annotation of `fixture_ip6config_service` from
  `IP4ConfigService` to `IP6ConfigService`.
- Fix recurring "excepiton" typo in tests/utils/test_exception_helper.py.

* tests: verify backup cleanup on permission error

After `test_new_backup_permission_error` raises `BackupPermissionError`,
assert that no tarfile was left behind and `tmp_path` is empty. The
previous version only checked that the exception was raised, which
missed any regression where a partial tarfile would survive the failed
create.

* tests: rename DNS_GOOD_V6 to DNS_V6_UNSUPPORTED

The constant was named "good" but its tests assert that the URLs are
rejected by the DNS validator. The IPv6 URLs are well-formed but
currently rejected because IPv6 doesn't work with the Docker network
(see `dns_url` in supervisor/validate.py). Rename the constant and the
related test to make the intent obvious.
