Pull request overview

Adds clearer cross-space provenance cues in the UI so users can tell when a resource shown in search/browse belongs to a different (non-default) space, and provides a direct link to view that resource in its “home” space.

Changes:

• Adds a “space” label on index/list cards for resources that belong to a different space (space_tag helper used across multiple masonry partials).
• Adds a reusable sidebar partial (common/_space_info) to show space details + a “View in space” link on show pages.
• Adds controller tests for the new Materials show-page space sidebar behavior, and adjusts layout CSS.

• This link opens a new tab (target: _blank) but does not set rel="noopener", which allows reverse-tabnabbing via window.opener. Use external_link/external_link_button, or add rel: 'noopener' to the link options.

      <%= link_to space.title, space.url, class: 'h5', target: :_blank %>
