Serialize forced coordinator refreshes per entry

NestQuestCoordinator.async_refresh holds a per-entry lock so
overlapping service-path refreshes never interleave; the queued pass
always publishes after the in-flight one.

+## Events
+
+NestQuest fires Home Assistant bus events so automations can react to a
+child's progress. Each payload carries `child_id`, `child_name`,
+`instance_id`, `quest_title`, the instance's `window`, `due_date`,
+`due_time`, and `occurred_at` (a strict UTC ISO-8601 timestamp).
+
+| Event | Fires when | Extra payload fields |
+|---|---|---|
+| `nestquest_quest_completed` | a quest is completed (an actual completion, never a re-complete no-op) | `was_on_time` (bool) |
+| `nestquest_quest_uncompleted` | an admin reverses a completion | — |
+| `nestquest_child_day_complete` | a completion clears the child's whole day (quests were owed and none remain; a zero-quest day never fires it) | `quests_due`, `quests_completed` |
+| `nestquest_quest_missed` | the nightly sweep marks a still-open past-due quest missed (integrated in a later release) | — |
+
+Example automation trigger:
+
+```yaml
+triggers:
+  - trigger: event
+    event_type: nestquest_child_day_complete
+conditions:
+  - condition: template
+    value_template: "{{ trigger.payload.child_name == 'Declan' }}"
+actions:
+  - action: notify.mobile_app_declans_phone
+    data:
+      message: "Every quest cleared — legendary!"

+
+Sits between the Feature 09 service gate and the typed

+validation and the UTC occurred-at stamp here, and never talk to the
+DAO or SQL directly.  This module is the only Feature-08 caller of
+:meth:`~.dao_instances.CompletionEventsDao.append`.  Completing an
+instance (no-op if already done) is :func:`complete_instance`;
+un-completing (no-op if already open) is :func:`uncomplete_instance`.
+Instance current state is derived from the latest event via
+:func:`instance_state` (``open`` / ``done`` / ``missed``); there is
+no status column.  ``missed`` is derived for past-due open instances
+(``due_date`` before HA-local ``today``) and is never stored as an
+event_type.
+
+Actor policy matches the schema CHECKs (D-008): ``actor_source`` is
+``'user'`` or ``'panel'`` only — never ``'service'``.  ``'user'``
+requires ``actor_user_id`` and forbids ``actor_child_id``; ``'panel'``
+requires ``actor_child_id`` (the tapped profile) and forbids
+``actor_user_id``.  Inverted shapes raise a field-naming ValueError
+before any write.
+
+``occurred_at`` is stamped UTC ISO-8601 at second precision with an
+explicit ``+00:00`` offset, matching the DAO's one accepted shape so
+lexicographic range queries stay exact.  ``was_on_time`` is required
+(True/False) for completed events; un-completions may pass None.  There
+is no permission check here (that is Feature 09).

+Naming contract (design/ENTITIES-AND-SERVICES.md §1): the design table
+documents the entity_id shape ``sensor.nestquest_<child>_quests_due_today``.
+Home Assistant derives entity_id from the entity NAME and exact
+entity_id strings are not directly controllable, so names are spelled
+to slug into the documented shape — ``NestQuest Ada quests due today``
+slugs to ``sensor.nestquest_ada_quests_due_today`` — while the

+database id, never the display name, so a rename never orphans an
+entity's history.  The design table is the visual contract; this
+module spells names so HA's default slugging produces it.
+
+Every sensor reads ONLY ``coordinator.data`` (one
+:class:`~.coordinator.ChildDaySnapshot` per active child); no entity
+queries the database, so one refresh updates the whole board
+coherently.  The due-today sensor additionally carries the child's
+day payload as attributes: ``instances`` is the panel shape of
