feat: expand color system to 53 colors/10 palettes, add grid/slide themes, and README gallery

Replace the 16-color / 3-palette system with the full Civilytics design system: 53 named colors (full navy, ember, violet ramps plus teal, plum, moss, brass supporting hues) and 10 visualization palettes (qual, qual_warm, qual_cool, seq_ember, seq_navy, seq_violet, seq_paper_ink, div_navy_ember, div_violet_ember). Enrich theme_civilytics() with grid and paper_bg parameters, add theme_civilytics_slide() for presentations, and load all four brand fonts (Inter, Libre Franklin, Source Serif 4, JetBrains Mono). Add README.Rmd with rendered gallery showing all palettes, theme variants, grid options, dark/slide modes, facets, and scale usage.
