feat(calendarium@kami911): add optional customizable border

New Appearance settings: "Draw a border around the desklet" with
adjustable width (1–10 px), color (colorchooser) and corner radius
(0–40 px). Off by default; when enabled the border and radius are applied
to the container style alongside the existing background/opacity styling.
