package.

additional information if needed from a user's published

CI was using a test of ! -s which appeared to give a false positive
and try to push when it shouldn't. I changed it to -z which checks
for an empty string instead.

Introduced an new label to set the scaling factor that is used to calculate th proportions, setting it to 0 also allows to disable scaling.
Updated the tests to reflect the changes and added a new test which shows that setting the scaling factor to 0 indeed does disable scaling.
Ensured that the scaling factor is always between [0 and 100].

Fixed the UI so that when an error occurs, the tab automatically changes
to the manual tab in order to show the errors.

effect to the coverage for `go test`. Therefore, moved the tests inside
the same directory as the test target.

Get is a supported method so this test failed, I've now changed
this to an unsupported method - i.e. HEAD to trigger the error
and keep the test.
