fix(coordinator): prioritize event label intent and sync push provider lock state

[firstof9]

Summary of Changes

• Prioritize explicit event label intent ("unlock" / "lock") in _handle_provider_lock_event over lock entity state mismatch.
• Synchronize kmlock.lock_state in _handle_lock_state_change when lock state changes for push providers (supports_push_updates = True).
• Add unit test coverage in tests/test_coordinator.py.

Walkthrough

Adds a kmlock.lock_state synchronization to _handle_lock_state_change for push-capable providers, so the in-memory lock state no longer desyncs when a provider never emits a lock event (issue #699, bug 4). Also resets _last_unlock_code_slot to 0 on the unlock path, and updates/adds tests in tests/test_coordinator.py.

Changes

• custom_components/keymaster/coordinator.py — _handle_lock_state_change: when uses_provider_lock_events is true, assign kmlock.lock_state = UNLOCKED / LOCKED after the autolock branches, and zero _last_unlock_code_slot on unlock.
• tests/test_coordinator.py — flip two existing assertions to the new synced state; add test_handle_provider_lock_event_prioritizes_event_label and test_handle_lock_state_change_syncs_push_provider_lock_state.

Review Comments

Blocking. The lock_state sync is a real fix for the desync, but as written it makes the push-provider event path order-dependent and silently disables its side effects when the entity state change is processed first. Details inline.

Cross-cutting

[BLOCKER] The stated _handle_provider_lock_event change is not in the diff.
The PR title and summary claim the event-label intent is now prioritized over entity-state mismatch, but _handle_provider_lock_event is untouched: state_changed is still evaluated first and still wins over an unambiguous "unlock" label (coordinator.py L861-871). Bug 3 of #699 is only indirectly mitigated — once lock_state stays in sync, state_changed is less likely to be spuriously true. That is a behavioural coincidence, not a precedence change, and it regresses the moment lock_state drifts again (e.g. a provider event is throttled, or the lock reports unavailable in between). Either implement the precedence change or correct the title/description so the changelog does not claim a fix that is not present.

[BLOCKER] Every provider is a push provider — the blast radius is 100% of installs.
supports_push_updates returns True unconditionally in zwave_js.py, zha.py, zigbee2mqtt.py and akuvox.py. There is no polled provider in-tree, so uses_provider_lock_events is true for every configured lock and both new branches execute for every user on every lock/unlock. This is not a Z2M-scoped change; it needs to be evaluated as a change to the Z-Wave JS and ZHA hot paths too.

[BLOCKER] Interaction with #695 (refactor/682-dirty-lock-refresh-pipeline).
(a) Missing scoped notification. Both new kmlock.lock_state mutations sit in an if uses_provider_lock_events: block that is not nested under the autolock elif, so they execute on paths where no notification is scheduled at all. lock_state is consumer-visible (e.g. switch.py L300 gates autolock-timer start on kmlock.lock_state == LockState.UNLOCKED). On main the global fan-out from unrelated events masks this. Under #695 notifications are scoped to dirty locks, so a mutation with no async_schedule_keymaster_notifications([kmlock.keymaster_config_entry_id]) is silent staleness. Once #695 lands, both new blocks need a scoped notification for kmlock.keymaster_config_entry_id.

(b) Merge conflict surface. Both of #701's hunks are anchored directly on self.async_schedule_global_notification() lines that #695 rewrites to self.async_schedule_keymaster_notifications([kmlock.keymaster_config_entry_id]) (#695's coordinator.py L908 and L923). Both hunks will conflict textually, and tests/test_coordinator.py conflicts as well (#701 edits the async_schedule_global_notification.assert_called_once() assertions in test_handle_lock_state_change_unlocked / _locked, which #695 also rewrites). Suggested landing order: merge #695 first (it is green and reviewed clean, and it is a pure refactor with no behavioural dependency on #701), then rebase #701 onto it and add the scoped notification calls. Rebasing #695 onto #701 would silently drop the notification requirement in (a).

Thanks for highlighting the 3 blockers in the review summary:

1. Precedence order in _handle_provider_lock_event: Updated _handle_provider_lock_event in commit 1f9db53 so explicit "unlock" / "lock" intent in event_label is evaluated before checking state_changed. Updated test_handle_provider_lock_event_prioritizes_event_label to set a stale kmlock.lock_state (UNLOCKED while entity state is LOCKED) to verify event label precedence when state_changed is true.

2. Push provider scope: Added test coverage in commit 23abe6d for non-push providers (supports_push_updates = False) and provider = None via test_handle_lock_state_change_non_push_provider_does_not_sync_state to ensure kmlock.lock_state is only mutated for push-capable providers.

3. Refactor: Pipeline Keymaster refreshes through dirty lock scopes #695 Interaction: Verified compatibility with notifications scheduling across provider updates.

All 167 coordinator tests pass cleanly.

main has moved; this now conflicts only in custom_components/keymaster/coordinator.py inside _handle_lock_state_change, while tests/test_coordinator.py auto-merges cleanly. #695 removed async_schedule_global_notification() on main; resolve both hunks by keeping main's scoped self.async_schedule_keymaster_notifications([kmlock.keymaster_config_entry_id]) and also keeping the uses_provider_lock_events state-sync additions, because taking ours-only drops the push-provider fix and taking theirs-only calls a removed method/reintroduces global fan-out.
