feat: add shape fill/stroke transparency, RGBA color picker, and dash styles

Closes #193. Shapes now support no-fill and no-stroke toggles for drawing
outlines or fill-only shapes. Adds RGBA color picker with opacity control,
stroke dash styles (solid/dashed/dotted), and i18n for all shape labels.
