 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

# Configuration
Adaptive Lighting supports configuration through both YAML and the Home Assistant UI, with identical option names in both methods.
## Basic Configuration
The simplest setup uses the Home Assistant UI. Go to **Settings** → **Devices & Services** → **Add Integration** → **Adaptive Lighting**. No `adaptive_lighting:` entry is needed in `configuration.yaml`.
## YAML Configuration
Alternatively, you can specify lights and options in `configuration.yaml`:
```yaml
adaptive_lighting:
- name: "Living Room"
lights:
- light.living_room_ceiling
- light.living_room_lamp
```
## All Options
All configuration options are listed below with their default values. These options work identically in both YAML and the UI.

| `transition` | Duration of transition when lights change, in seconds. 🕑 | `45` | `float` 0-6553 |
| `initial_transition` | Duration of the first transition when lights turn from `off` to `on` in seconds. ⏲️ | `1` | `float` 0-6553 |
| `min_brightness` | Minimum brightness percentage. 💡 | `1` | `int` 1-100 |
| `max_brightness` | Maximum brightness percentage. 💡 | `100` | `int` 1-100 |
| `min_color_temp` | Warmest color temperature in Kelvin. 🔥 | `2000` | `int` 1000-10000 |
| `max_color_temp` | Coldest color temperature in Kelvin. ❄️ | `5500` | `int` 1000-10000 |
| `prefer_rgb_color` | Whether to prefer RGB color adjustment over light color temperature when possible. 🌈 | `False` | `bool` |
| `sleep_brightness` | Brightness percentage of lights in sleep mode. 😴 | `1` | `int` 1-100 |
| `sleep_rgb_or_color_temp` | Use either `"rgb_color"` or `"color_temp"` in sleep mode. 🌙 | `color_temp` | one of `['color_temp', 'rgb_color']` |
| `sleep_color_temp` | Color temperature in sleep mode (used when `sleep_rgb_or_color_temp` is `color_temp`) in Kelvin. 😴 | `1000` | `int` 1000-10000 |
| `sleep_rgb_color` | RGB color in sleep mode (used when `sleep_rgb_or_color_temp` is "rgb_color"). 🌈 | `[255, 56, 0]` | RGB color |
| `sleep_transition` | Duration of transition when "sleep mode" is toggled in seconds. 😴 | `1` | `float` 0-6553 |
| `transition_until_sleep` | When enabled, Adaptive Lighting will treat sleep settings as the minimum, transitioning to these values after sunset. 🌙 | `False` | `bool` |
| `sunrise_time` | Set a fixed time (HH:MM:SS) for sunrise. 🌅 | `None` | `str` |
| `min_sunrise_time` | Set the earliest virtual sunrise time (HH:MM:SS), allowing for later sunrises. 🌅 | `None` | `str` |
| `max_sunrise_time` | Set the latest virtual sunrise time (HH:MM:SS), allowing for earlier sunrises. 🌅 | `None` | `str` |
| `sunrise_offset` | Adjust sunrise time with a positive or negative offset in seconds. ⏰ | `0` | `int` |
| `sunset_time` | Set a fixed time (HH:MM:SS) for sunset. 🌇 | `None` | `str` |
| `min_sunset_time` | Set the earliest virtual sunset time (HH:MM:SS), allowing for later sunsets. 🌇 | `None` | `str` |
| `max_sunset_time` | Set the latest virtual sunset time (HH:MM:SS), allowing for earlier sunsets. 🌇 | `None` | `str` |
| `sunset_offset` | Adjust sunset time with a positive or negative offset in seconds. ⏰ | `0` | `int` |
| `brightness_mode` | Brightness mode to use. Possible values are `default`, `linear`, and `tanh` (uses `brightness_mode_time_dark` and `brightness_mode_time_light`). 📈 | `default` | one of `['default', 'linear', 'tanh']` |
| `brightness_mode_time_dark` | (Ignored if `brightness_mode='default'`) The duration in seconds to ramp up/down the brightness before/after sunrise/sunset. 📈📉 | `900` | `int` |
| `brightness_mode_time_light` | (Ignored if `brightness_mode='default'`) The duration in seconds to ramp up/down the brightness after/before sunrise/sunset. 📈📉. | `3600` | `int` |
| `take_over_control` | Pause adaptation of individual lights and hand over (manual) control to other sources that issue `light.turn_on` calls for lights that are on. 🔒 | `True` | `bool` |
| `take_over_control_mode` | The adaptation pausing mode when other sources change brightness and/or color of lights. `pause_all` always pauses both brightness and color adaptation. `pause_changed` pauses the adaptation of only the changed attributes and continues adapting unchanged attributes, e.g., continues color adaptation when only brightness was changed. | `pause_all` | one of `['pause_all', 'pause_changed']` |
| `detect_non_ha_changes` | Detects and halts adaptations for non-`light.turn_on` state changes. Needs `take_over_control` enabled. 🕵️ Caution: ⚠️ Some lights might falsely indicate an 'on' state, which could result in lights turning on unexpectedly. Note that this calls `homeassistant.update_entity` every `interval`! Disable this feature if you encounter such issues. | `False` | `bool` |
| `autoreset_control_seconds` | Automatically reset the manual control after a number of seconds. Set to 0 to disable. ⏲️ | `0` | `int` 0-31536000 |
| `only_once` | Adapt lights only when they are turned on (`true`) or keep adapting them (`false`). 🔄 | `False` | `bool` |
| `adapt_only_on_bare_turn_on` | When turning lights on initially. If set to `true`, AL adapts only if `light.turn_on` is invoked without specifying color or brightness. ❌🌈 This e.g., prevents adaptation when activating a scene and marks the light as manually controlled. If `false`, AL adapts regardless of the presence of color or brightness in the initial `service_data`. Needs `take_over_control` enabled. 🕵️ | `False` | `bool` |
| `manual_control_on_external_turn_on` | Treat turn-ons without a matching Home Assistant `light.turn_on` context as manual control. Normal manual-control resets apply. Still allows `detect_non_ha_changes` for already-on lights. Needs `take_over_control` enabled. 🕵️ | `False` | `bool` |
| `reset_manual_control_on_sleep_mode_change` | Reset manual control when the sleep mode switch is toggled. Set to `false` to preserve manual control across sleep mode changes. 😴 | `True` | `bool` |
| `separate_turn_on_commands` | Use separate `light.turn_on` calls for color and brightness, needed for some light types. 🔀 | `False` | `bool` |
| `send_split_delay` | Delay (ms) between `separate_turn_on_commands` for lights that don't support simultaneous brightness and color setting. ⏲️ | `0` | `int` 0-10000 |
| `adapt_delay` | Wait time (seconds) between light turn on and Adaptive Lighting applying changes. Might help to avoid flickering. ⏲️ | `0` | `float > 0` |
| `skip_redundant_commands` | Skip sending adaptation commands whose target state already equals the light's known state. Minimizes network traffic and improves the adaptation responsivity in some situations. 📉Disable if physical light states get out of sync with HA's recorded state. | `False` | `bool` |
| `intercept` | Intercept and adapt `light.turn_on` calls to enabling instantaneous color and brightness adaptation. 🏎️ Disable for lights that do not support `light.turn_on` with color and brightness. | `True` | `bool` |
| `multi_light_intercept` | Intercept and adapt `light.turn_on` calls that target multiple lights. ➗⚠️ This might result in splitting up a single `light.turn_on` call into multiple calls, e.g., when lights are in different switches. Requires `intercept` to be enabled. | `True` | `bool` |
| `include_config_in_attributes` | Show all options as attributes on the switch in Home Assistant when set to `true`. 📝 | `False` | `bool` |
| `expand_light_groups` | Expand light groups to their members (`true`, default). Set `false` to send commands to the group and track manual control for the group. Explicit member targets in services stay individual targets. | `True` | `bool` |
