feat v1.39.0: pure light sources toggle on click by default

- resolveTapAction: no explicit action + domain light -> toggle (kettle
  et al. keep info via their non-light primary); explicit choice wins
- device dialog shows the effective default (defaultTap)
- unit tests updated (+1, 106); smoke_light_default_tap.mjs; docs
