feat(flutter): FabledSwordTheme ThemeExtension + Material 3 ThemeData

Widgets read tokens via Theme.of(ctx).extension<FabledSwordTheme>(). Material 3 ColorScheme bound to FabledSword tokens. Body text uses GoogleFonts.interTextTheme() so the fonts work without bundling .ttf files (offline-from-cold-launch is a separate question once #357 lands).
