Fix login by updating pysmarthashtag to 0.9.1

[Copilot]

Login fails with "Could not get login token from login page" / "Could not get location from auth page" because Smart moved the context parameter to a different redirect hop in their OIDC chain, breaking the parsing in pysmarthashtag 0.8.1.

• Dependency bump: pysmarthashtag 0.8.1 → 0.9.1, which includes a rewritten login flow that walks the full redirect chain and adaptive AIMD backoff to prevent WAF lockout during HA's retry loop (~80s interval)
• Integration version: left unchanged in this PR (release process handles version bumping)

Pull request overview

Updates the Home Assistant SmartHashtag integration metadata to consume the fixed upstream login flow by bumping the pysmarthashtag dependency and aligning the integration’s own version accordingly.

Changes:

• Bump dependency pysmarthashtag from 0.8.1 to 0.9.1 (login flow fix via upstream library).
• Bump integration version from 0.8.3 to 0.8.4.

Addressed in commit 3383c56: removed the manual integration version bump and kept only the pysmarthashtag==0.9.1 dependency update.
