bim.enable_wall_fillet_preview and its re-edit / toggle-openings gizmos gated
on is_a("IfcWall"), so two straight LAYER2 coverings (siding/cladding) couldn't
be filleted despite meeting every real requirement.
Drop the is_a("IfcWall") checks in _resolve_two_walls and the two fillet gizmo
polls; the actual gates (has_layer2_usage + is_straight_axis, and
is_fillet_corner_wall) are already class-agnostic. The generated corner
inherits the source element's type via add_occurrence, and fillet state lives
on EPset_Parametric, so a covering corner needs no wall-specific handling.
