fix: file pipeline status reporting and websocket updates (#589)

* feat: use file pipeline for upload and reprocess action

* fix: make file pipeline correctly report status events

* fix: duplication of transcripts_controller

* fix: tests

* test: fix file upload test

* test: fix reprocess

* fix: also patch from main_file_pipeline

(how patch is done is dependent of file import unfortunately)
