LIMS-2034: Remove unused columns from main DC query

[ndg63276]

JIRA ticket: LIMS-2034

Summary:

The large query for the main data collection page includes getting columns that are never used in the front end. The columns are also badly labelled, making editing them hard.

Changes:

• Don't fetch these values from the DataCollection table: voltage, c2aperture, c2lens, objaperture, magnification, numberofpasses, c1aperture, c1lens, c3aperture, c3lens, detectormode, slitgaphorizontal/vertical, binning, averagetemperature, nominalmagnification, nominaldefocus, imagesizex/y, pixelsizeonimage, phaseplate
• Remap the RobotAction columns status and message as runstatus and comments respectively
• Remove scon from the query as it never got anything from the db
• Label what remains for easier editing in future

To test:

• Go to a session with data collections, robot loads, edge scans and MCA spectra, eg /dc/visit/cm44137-1
• Check each of those types appear as expected
