feat(calendar): image/attachment per event, direct links, copy link, ImageModal component

- calendar_item schema: flyer → image (type: image), attachment (assetUrl)
- CalendarItemData: image + attachment fields
- event anchor IDs (#event-{slug}) with onMount hash scroll + auto-open
- share button uses direct calendar anchor URL
- copy link button (mdi:link-variant) copies anchor URL to clipboard
- ImageModal extracted as reusable component
- action buttons always show text (no expand-on-hover)
- onDestroy window guard (SSR fix)
