Fix composition, npips wiring, pip_scale double-apply, tile params, domino hover

- Plotly dice + domino: axis range, reversed y, ticks, and aspect ratio now
  apply on both owns-figure and caller-supplied-fig branches. Legend-reserved
  x-domain [0, 0.72] / [0, 0.74] is owns-figure-only; composition uses [0, 1].
- Remove `npips` from the public API. Slot count is inferred from
  `pips_order` / `pip_colors` / data — no post-preprocess overwrite.
- Collapse `tile_width` + `tile_height` into single `tile_size`. `_layout.py`
  takes `tile_frac` with (0, 1] validation.
- Categorical pip radius is `layout.base_pip_r` (no double pip_scale).
  `base_pip_r` already folds `pip_scale`; the backends were multiplying again.
- Plotly domino hover uses raw `size_value` via `customdata[4]` instead of the
  already-scaled `marker.size`.
- Regenerated categorical showcase PNGs reflect the corrected pip size.
