Kiss Lorand d2ca5d3a1e Fix hybrid tree first-layer support base behavior and expose density setting (#13454)
Fix hybrid tree first-layer support base flow and UI consistency

Fix incorrect first-layer generation for hybrid tree supports.

The support base on the first layer used brim flow instead of support material flow,
which could lead to incorrect extrusion behavior and wrong material usage in
multi-material prints.

Additionally, spacing and density for the regular support part were not consistently
derived from the actual first-layer support flow when first-layer and regular
line widths differed.

Hybrid-specific behavior is clarified:
- first-layer expansion applies only to the regular support part
- tree-only regions keep their existing behavior

The first-layer support pattern is aligned with normal and organic tree supports
to ensure consistent and meaningful density behavior.

Also make first-layer support expansion and density settings visible whenever
supports are enabled, as density was already affecting hybrid supports but was
hidden in the UI.
