Add bitmap font rendering via PNG tilesheet

Replace egui text rendering with a BitmapFont system: - Glyph.tile: u32 replaces ch: char; top-left pixel of PNG is background sentinel - BitmapFont loads/preprocesses PNG to opaque-white + transparent, tinted at render time - Default font: assets/vga-font-8x16.png (CP437, 8×16 tiles); placeholder generated if missing - Boards can specify a per-board font via [font] in their .toml file - Editor Board tab: "Font…" button opens font dialog (rfd file picker, tile dims, tilesheet preview) - Glyph picker: tile grid from active font replaces hardcoded ASCII char grid - map_file: TileIndex untagged enum accepts char or integer in palette entries Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
