fix: preserve Home Assistant area target exclusions (#1511)

* Exclude 'service' lights (entity_category) from area intercept turn-on

Fixes #1510

When Adaptive Lighting intercepts an area/label-targeted light.turn_on, the
intercept rewrites the call to target only the managed lights (see
modify_service_data), so Home Assistant's own handler turns on only those.
AL then re-issues light.turn_on for the remaining 'skipped' (unmanaged)
entities so they still come on.

The problem: HA excludes entities with an entity_category (config/diagnostic,
e.g. the Home Assistant Voice LED ring) from area/label expansion, but AL's
re-issue did not, so AL was the sole thing turning these service lights on.

Changes:
- Keep re-issuing skipped lights so unmanaged normal lights still come on,
  but filter out 'service' lights (entity_category set) from that re-issue.
- Add _is_service_light helper (registry-based) and divert a *managed*
  service light to 'skipped' in _separate_entity_ids, so it is excluded from
  the intercept turn-on while still being adapted when on.

* Add toggle regression test for service light exclusion from area intercept

Mirrors test_service_light_excluded_from_area_intercept_turn_on but uses
light.toggle: a service light (entity_category set) in an area must remain
off when AL intercepts an area toggle. The managed lights still toggle on.

* Only exclude service lights from indirect (area/device/label) expansion

Previously _is_service_light filtered service lights unconditionally, which
also excluded a service light explicitly named in `entity_id`. Home
Assistant only excludes such lights from indirect area/device/label expansion
and turns them on when directly targeted, so AL must mirror that: service
lights are now excluded from the intercept/re-issue only when not directly
targeted (`direct_entity_ids`).

Adds a regression test for the direct-target case.

* Use if/elif/else for indirect service-light exclusion; inline check

Address review: collapse the two separate `if is_service`/"if not
is_service" into an `if/elif/else` chain (ruff PLR5501) and inline the
service check as `self._is_service_light(...) and entity_id not in
direct_entity_ids`, which conceptually is `is_indirect_service`.
Matches HA's indirect-only exclusion and keeps the flow simple.

* Filter service lights directly in _get_entity_list expansion

Move service-light filtering to the single expansion site
AdaptiveLightingManager._get_entity_list. Area/device expansion is the
only place where HA excludes entity_category lights, so filtering there
mirrors HA and makes the later direct_entity_ids / skipped_normal guards
unnecessary. Explicit entity_id targets bypass expansion and therefore
still turn on service lights, matching HA.

Fully reverts the direct_entity_ids / skipped_normal addition per review.
