fix(DICOM PDF and Video): fixes for local DICOM load and remote data sources (#3374)

* fix(DICOM PDF and Video)
- added retrieve.directURL for local DICOM load data source; it returns a data URL
- fixed various checks for video using transfer syntaxes and SOP class UID with number of frames
- added call to 'rendered' endpoint for those data sources that support it; others get BulkDataURI

* Added DOC (PDF) and OT (for video in particular) to list of non-image thumbnail modalities.

* Fixed broken e2e tests.
