LIMS-1463: Always display Mesh3D data collections as grid scans

[ndg63276]

JIRA ticket: LIMS-1463

Summary:

When Hyperion adds a Mesh3D experiment to ISPyB, Synchweb initially displays it as a rotational data collection, only updating to a grid scan style after a refresh. We should detect that it is a grid scan immediately.

Changes:

• Treat the experiment type Mesh3d (ie hyperion grid scans) the same as Mesh (ie GDA grid scans)
• Force both to display as grid scans, irrespective of the axis range and number of images

To test:

• View a stopped Hyperion grid scan (eg /dc/visit/cm37235-4/dcg/13099843) check it displays in the style of a grid scan, ie space for a diffraction image and space for a crystal snapshot, no space for a graph of spot counts
• View a completed Hyperion grid scan (eg /dc/visit/cm37235-4/dcg/13087189), check it displays in the style of a grid scan (ie unchanged)
• View a GDA grid scan (eg /dc/visit/cm37236-4/id/15488302), check it displays in the style of a grid scan (ie unchanged)
• View a "SAD" data collection (eg /dc/visit/cm37236-4/id/15488314), check it is unchanged from production)
• View a "Serial Fixed" (eg /dc/visit/cy37017-1/id/15324649) and "Serial Jet" (eg /dc/visit/cm37275-4/id/14945838) experiment, check they are unchanged from production
