feat: expose per-attribute manual_control as state attributes

[jaredjxyz]

Summary

Adds two new read-only state attributes on the AdaptiveSwitch entity:

• manual_control_brightness: list of light entity_ids whose brightness axis is currently in manual override.
• manual_control_color: same, for the color axis.

These mirror the existing `manual_control` attribute (which is a union of both axes) by exposing the `LightControlAttributes` bitfield that AL already tracks internally per-light.

Why

The existing `manual_control` state attribute and the `adaptive_lighting.manual_control` event are useful, but neither lets a template or dashboard see which axis is paused without subscribing to events. This is especially relevant with `take_over_control_mode: pause_changed`, where one axis can be manual while the other still adapts (e.g. user dimmed brightness manually but AL should keep tracking color temp).

After this change:

{# Was just brightness manually changed, with color still adapting? #}
{{ 'light.bedroom' in state_attr('switch.adaptive_lighting_bedroom', 'manual_control_brightness') }}

Implementation

~12 lines in custom_components/adaptive_lighting/switch.py extra_state_attributes. Uses the already-imported LightControlAttributes (no new imports).

Tests

Extended test_manual_control in tests/test_switch.py to assert that the new attributes reflect the bitfield after a manual brightness change and after a clear via adaptive_lighting.set_manual_control.

Test plan

• `test_manual_control` updated and asserts both new attributes
• No new platform; no breaking changes
• Existing `manual_control` attribute behavior unchanged
