Replaced GTK3 palette font styling with CSS-compliant properties derived from PangoFontDescription, avoiding the deprecated Pango font: syntax in generated CSS.

Browse Source 
Added a GTK3-only helper to translate Pango font fields into font-family, font-size, font-style, font-weight, font-variant, and font-stretch CSS declarations while preserving GTK2 behavior under #if !HAVE_GTK3.
Reused the GTK3 font CSS helper in the main UI font styling path to eliminate remaining Pango font: shorthand usage that triggers GTK3 theme parsing warnings.
Exposed the GTK3 font CSS helper in gtkutil so callers can emit CSS-compliant font properties consistently.
