Fix VEOIBD testing instance (#234)

* Update dca_config.json

still getting a server disconnect error when selecting VEOIBD DCC with the testing instance of DCA. Upon further review I noticed some additional differences btwn the prod/main branch version of dca_config under the schematic parameters. I've changed this version of the file starting at line 18  to match what is in main branch

* add schematic global config

* add link to data dictionary site

* add missing comma

* add dca model_submit params

* replace file_annotations_upload with use_schema_labels

* remove use_schema_labels from model_submit

* fix accidental deletion of table manipulation param

* correct for suspected breaking change
