Add an All Lights entity for the whole chain

[bharvey88]

Version: 26.8.26.2

What does this implement/fix?

Home Assistant exposed only the five zone partitions (Body, Mouth, Nose, Eyes, Hat), with no way to control all 37 LEDs at once. H-1 and H-2 both expose their strip as a single light; H-3 was the only ornament without a whole-ornament control.

Adds a sixth partition spanning the full chain:

  - platform: partition
    id: all_lights
    name: "All Lights"
    default_transition_length: 0s
    segments:
      - { id: led_chain, from: 0, to: 36 }
    effects: *led_effects

It sits alongside the zones rather than replacing them, and the parent led_chain stays internal: true. Partitions write into the parent's buffer and the parent does the single transmit, so this adds no second driver on GPIO3. Overlapping coverage is valid: the partition platform validates only that from <= to and that both are inside num_leds.

Three supporting changes keep the entity state honest:

• all_lights_off clears it, so it does not report on after a song ends and the zones go dark
• on_shutdown in both variant files clears it, so a lit master does not survive into deep sleep
• each play_song_* turns it off first, because a running All Lights effect and the zone effects would otherwise both rewrite the same buffer every 100 ms

All Lights sorts above Body Light on the Home Assistant device page.
