feat: share links visible on plants/containers; container image gallery

- Fix ShareButton silently swallowing errors from createShareLink; now
  shows inline error text so failures are visible to the user
- Add getShareLinksForEntity server action and EntityShareLink type to
  _core/share.ts
- Add ShareLinkList component — renders active share links per entity
  with per-row Revoke; renders nothing when empty
- Wire ShareLinkList into plant and container detail pages (loaded
  server-side in parallel with the entity fetch)
- Add images jsonb column to garden_containers schema + migration 0018
- Add addContainerImage / removeContainerImage / setContainerPrimaryImage
  server actions mirroring the plant image pattern (10-image cap, first
  upload auto-sets cover)
- Update ContainerDetailDto, listContainers, getContainer to include images
- Rewrite ContainerDetail with Info/Gallery tabs; Gallery tab mirrors
  plant gallery (3-col grid, star/X overlays, upload button, counter)
- Update ContainerShareData and container renderSharedView to show cover
  image hero and secondary image grid on public share pages
