no issue
When scheduling a post to publish+send the "view online" link was pointing at https://site.com/404/ rather than the published post's url.
The problem occurred because the `/schedules/` endpoint wraps it's post read+edit calls in a transaction. Context:
- when a post is published with with the "send email" option the email record is immediately generated and added to the API response, as part of the email record generation we render the email content including fetching the url for the "view online" link
- urls for all resources are handled by our `url` service, that service updates it's internal cache based upon model events such as the "edited" event triggered when a post is published
- if the posts API controller is given a transaction, the email record is also generated inside of that transaction however at this point the `url` service will not have been updated because the post record hasn't been committed meaning it has no available url for the post
Fix:
- removed the `models.Base.transaction()` wrapper around the post read+update in the `/schedules/` API controllers
- we don't need a transaction here. It was added as protection against another write request coming in between the `/schedules/` controller reading a post and publishing a post but we already have protection against that in the form of collision detection - if a write request comes in and commits between the schedules controller reading the post and updating it, the scheduler's update call will fail with a collision error at which point the scheduler itself should retry the request which could then publish the post successfully if everything else is in order
* moved `server/config` to `shared/config`
* updated config import paths in server to use shared
* updated config import paths in frontend to use shared
* updated config import paths in test to use shared
* updated config import paths in root to use shared
* trigger regression tests
* of course the rebase broke tests

- Not all of them need to be updated; only updating the ones that are
causing failures
* fixed errors import being shadowed by local scope
* Updated scheduler to use v2 API by default
* Updated scheduling for post/page resource types
* Extended base method to take options param with token and jwt options
* Updated token expiration to 6 hours after publish/blog start time to allow retries
