feat: add expand_light_groups option (#1462)

* feat: add expand_light_groups option

Some light group entities act as a proxy that must receive a single combined
`light.turn_on` call to function correctly — virtual mixers like
<https://github.com/mion00/color-temperature-light-mixer> for instance,
that blend a warm and a cold white channel into one entity. In such setups the
individual member entities only expose `ColorMode.BRIGHTNESS`, so sending
separate per-member commands bypasses the mixing logic.

Setting `expand_light_groups: false` keeps the group entity in `self.lights`
instead of expanding it to its members. Adaptation commands go to the group,
and the interceptor no longer skips group entities for that switch.

Default is `true` — no behaviour change for existing configurations.

* tests: regression test for expand_light_groups=False

_switches_with_lights was expanding the incoming entity_id globally,
causing the switch to never be found when expand_light_groups=False

* Resolve group targets consistently across adaptation paths

* Discard delayed group events after target changes

* Stabilize delayed group target regression test

Additionally, enabling `detect_non_ha_changes` allows Adaptive Lighting to detect all state changes, including those made outside of Home Assistant, by comparing the light's state to its previously used settings.
The `adaptive_lighting.manual_control` event is fired when a light is marked as "manually controlled," allowing for integration with automations 🤖.
With `expand_light_groups: false`, manual control belongs to the group. A direct member change cannot pause adaptation for only that member; use group-level manual control or enable expansion for individual tracking.
Explicit member targets in Adaptive Lighting services stay individual targets and do not mark or command the whole group.
Changing expansion at runtime discards tracking and pending adaptation for targets no longer used by any profile.
The Adaptive Lighting switch exposes these read-only attributes for its lights:
- `manual_control`: lights with any attribute marked as manually controlled.
