feat(config): add bonsai animation configuration fields

Introduces eleven `bonsai_*` configuration fields (pot style, life,
multiplier, leaf glyphs, five colors, step / finish-pause timings)
along with their documentation in the example config.ini. The fields
are unused at this point; subsequent commits wire them into the
animation widget and renderer.
