Add bundled TTF fonts, page geometry, column allocator and render model

Static TTF fonts (IBM Plex Sans/Mono, Noto Devanagari/Kannada) with a fontkit-generated manifest, a verifier and OFL licences. Every family registers a normal and italic source so fallback stacks cannot throw. Adds A4/Letter geometry with margin presets, an exact column allocator, deterministic Indian-grouping money and date formatting, text sanitising and a pure buildRenderModel.
