[CURVE]: Cyclic imports

[Cloud7050]

The linter is reporting cyclic imports between bundles/curve/curves_webgl.ts and bundles/curve/types.ts.

The latter defines the types DrawMode, ScaleMode, and CurveSpace, which are used in the former, but at the same time, the former builds up to defining Curve and CurveDrawn, which the latter needs. Some refactoring may be in order, to resolve this and better fit each file's purpose.

The curve module will be replaced by plotly. We can remove curve once all missions/quests are migrated. We can then close this issue.

Should we remove it? We can migrate to plotly for sure but I think it's worth keeping the "legacy" modules

[martin-henz]

Yes, we can keep curve around. No need to rush removal.
