[BUG] get_login_info fails: SSO page now uses single-quoted assignments #176

Describe the bug
Since 20 Oct 2026, https://sso.hivehome.com/ writes its config as
window.HiveSSOPoolId = 'eu-west-1_…'; (spaces around =, single quotes) instead of
window.HiveSSOPoolId="…",. Login info can no longer be parsed, so every setup fails
before authentication. Reauth/2FA can't help.

• Released 1.0.9 (pinned by Home Assistant): the find-and-replace JSON build fails with
  Failed to get login info: Expecting value: line 1 column 20 (char 19), then
  AttributeError: 'NoneType' object has no attribute 'get' at
  hive_auth_async.py self.__pool_id = self.data.get("UPID").
• dev (2.0.0 betas): _SSO_ASSIGNMENT only matches double-quoted values, so
  get_login_info() hits a KeyError and returns None. Same outcome.

Expected behavior
get_login_info() parses HiveSSOPoolId and HiveSSOPublicCognitoClientId in either format.

Additional context
Fix: allow either quote in _SSO_ASSIGNMENT:
re.compile(r"""window\.(\w+)\s*=\s*["']([^"']*)["']""")
Tested against the live page and with a new unit test; full suite and pre-commit pass.
I'll open a PR against dev. Home Assistant would also need a release and a version bump.
A hot-patched 1.0.9 is working on HA Core 2026.10 (Python 3.14).
