generate_ha: on/off lighting becomes a light; brightness-only "lights" go to review instead of invalid YAML

Found on a real 1312-GA house, measured on all seven corpus projects.

B. Lighting on/off (1.001, lighting category) is emitted as a Home Assistant light with
   address + state_address, not a switch. The HA KNX light platform documents exactly
   that ("Simple light"). suggest.py already proposed light for these; the two engines
   disagreed. Without status it is reported as light_without_status.

D. A 5.001 lighting GA with no on/off GA in its zone produced a light with only
   brightness_address. Home Assistant requires address on a KNX light, so that YAML was
   invalid. 51 of them across six projects, mostly motion-detector parameters on 5.001.
   They now go to review as light_without_switch, and the brightness status is no longer
   consumed for an entity that does not exist, so it surfaces as not_mapped.

Corpus, before -> after: lights without address 51 -> 0 everywhere; no address lost from
YAML or review on any project; switch -> light moves of 220 (house), 205, 62, 43, 17, 10,
13. test_pipeline B1 fixture gains its on/off GAs (it encoded an invalid light) plus a
test for the review route. CHANGELOG also records fix A from 481bab0.
