Add GeomAdaptor_TransformedCurve as a new base class for BRepAdaptor_Curve that wraps a GeomAdaptor_Curve (or Adaptor3d_CurveOnSurface) with an applied gp_Trsf transformation. This mirrors the existing GeomAdaptor_TransformedSurface pattern for curves. Refactor the adaptor evaluation API across Adaptor3d_Curve and Adaptor3d_Surface hierarchies so that EvalD0/D1/D2/D3/DN are the primary virtual evaluation methods: - Adaptor3d_Curve: Value, D0-DN become non-virtual inline wrappers delegating to EvalD*. Base EvalD* implementations now throw Standard_NotImplemented instead of calling D*. - Adaptor3d_Surface: same pattern applied symmetrically. - Adaptor3d_CurveOnSurface: removes Value/D0-DN overrides (inherited from base); adds EvalD0/D1/D2/D3/DN marked final with the full dispatch logic. - Adaptor3d_IsoCurve: removes Value/D0-DN overrides; adds EvalD* final with iso-curve projection logic (IsoU selects D1V/D2V/D3V, IsoV selects D1U/D2U/D3U). - GeomAdaptor_Curve: removes Value/D0-DN overrides (now inherited inline); EvalD* remain final with BSpline cache and analytical dispatch logic. - GeomAdaptor_Surface: removes Value/D0-DN overrides (now inherited inline); EvalD* remain final with BSpline cache and analytical dispatch logic. - GeomAdaptor_TransformedCurve: overrides EvalD* with transform-and-dispatch logic; no need to override Value/D0-DN (inherited from Adaptor3d_Curve). - GeomAdaptor_TransformedSurface: removes Value/D0-DN overrides (now inherited inline). - BRepAdaptor_Curve: refactored to inherit GeomAdaptor_TransformedCurve, removing all duplicated evaluation and geometry-extraction method implementations. - BRepAdaptor_CompCurve: removes Value/D0-DN overrides; adds EvalD* final with compound-curve parameter mapping and derivative scaling logic. - ProjLib_ProjectOnPlane: removes Value/D0-DN overrides; adds EvalD* final delegating to the projected result adaptor or the OnPlane_* free functions. - GeomFill_SnglrFunc: removes Value/D0-DN overrides; adds EvalD* final implementing the C'(t) x C''(t) singular function with ratio scaling. - ChFiDS_ElSpine: removes Value/D0-D3 overrides; adds EvalD0-D3 final delegating to the internal GeomAdaptor_Curve member. - BiTgte_CurveOnEdge: removes Value/D0-DN overrides; adds EvalD* final. - BiTgte_CurveOnVertex: removes Value/D0-DN overrides; adds EvalD* final (D1-DN throw Standard_NotImplemented as the curve represents a degenerate point). - HelixGeom_HelixCurve: removes Value/D0-D2/DN overrides; adds EvalD0/D1/D2/DN final with trigonometric helix evaluation. Add GTest coverage for GeomAdaptor_TransformedCurve: point/derivative evaluation with transformation, curve-on-surface path, GeomGridEval_Curve batch evaluation.
