JIRA ticket: LIMS-2077

Summary:

Groups of grid scans for Xray centring correctly show the number of boxes in 3 dimensions on the main page, but when you click into the group, it should show the individual grid scans with the 2d number of boxes.

Changes:

• Put the 3rd dimension of the grid scan group (STEPS_Z) into a separate span
• Hide the span if viewing inside a data collection group

To test:

• Go to a visit with grid scan groups eg /dc/visit/cm40608-5
• Check the groups of grid scans on the main page show 3 dimensions for Grid Scan Size, eg 30 x 10 x 15
• Click into one of the groups eg /dc/visit/cm40608-5/dcg/17214375
• Check each grid scan only shows 2 dimensions eg 30 x 10 or 30 x 15
• Click into an individual grid scan eg /dc/visit/cm40608-5/id/20910753
• Check it only shows 2 dimensions again eg 30 x 10
