fix: csv upload should not save file

[golanglemonade]

• fixes csv upload, the files were being saved to the files schema and then unable to be read for input. These files should instead be skipped by the middleware
• fixes labeler that apparently did not save on my last PR

Confirmed opencloud-cloud works correctly again to seed data:

task cli:init                                          
task: [cli:init] go run cmd/cli/main.go seed init
