feat(tabletop): author rotation and tilt angles in degrees

Convert bgm rotation and tilt values to radians only at the three.js
boundary, so the format's angles are authored in degrees.

- `align` — `start`, `end`, or `center` of the curve.
- `steps` — the maximum number of parts per curve length unit. Defaults to
`1`. See the positioning process below.
- `tilt` — rotation in radians per shown part about the card's local Y (long)
- `tilt` — rotation in degrees per shown part about the card's local Y (long)
axis. Each part tilts `tilt` more than the previous, fanning the stack so
its edges stay visible. It applies even without a `curve`, so a bare `tilt`
fans a straight pile.
