Move Additional Configs to Settings table

[slominskir]

There are some environment variables that should instead be settings such that it is easier for admins to configure, and without restarting the app server. Namely:

• JAM_EMAIL_SENDER
• JAM_COMPONENT_DETAIL_URL
• JAM_COMPONENT_QUERY_URL
• JAM_USER_QUERY_URL
• (PREFIX)_DOC_CSV

The JAM_USER_QUERY_URL in particular is noticeable at the moment as I'd really like to set it on the staged app, but I really don't want to restart the shared app server instance!

Also, the DOC_CSV (part of smoothness weblib) would be nice too. Been asked to update help page docs to point to Event Notification Explanation wiki. Currently set in the ENV, which means requires app server restart!

Restarted App Server to update JAM_USER_QUERY_URL and (PREFIX)_DOC_CSV. Might make sense to punt on this for now. The smoothness weblib envs should be fixed upstream anyways.
