RUN-2148: UI:Next: jobs list SCM status fixes

[gschueler]

Is this a bugfix, or an enhancement? Please describe.

Fix two issues with the SCM status shown in Jobs list (Next UI):

• Error message from invalid configuration or lack of access credentials should be shown in GUI
• SCM status shown for a job was incorrect in some cases

Fix one issue with Git plugin:

• if no ssh key or password path is configured, the GUI should not show an error about not having access to the path

---

test setup:

Create a source repo that can be used for both Import or Export:

# create src git repo "gitrepo"
mkdir gitrepo
(cd gitrepo && git init --bare )
mkdir gitcheckout
git clone $PWD/gitrepo gitcheckout
cd gitcheckout
git commit --allow-empty -m 'first'
git push origin -u

configure SCM export/import in the project:

• Base directory: (use a file path for scm export, such as `$RDECK_BASE/projects/$project/export)
• git URL: file:///path/to/gitrepo
• Base branch on: master
• branch: master

To test misconfigured key access:

under Authentication section, add a SSH Key Storage Path that doesn't exist.

In the Job list gui (next UI) there should be a warning icon with a message about the error. (Compare to legacy UI)

Fix confirmed! Thank you for the instructions regarding how to set up SCM, as I wasn't aware that the project had this functionality.

Noted one tiny nit, but it's an optional fix. 🚀
