FIX: Update navbar action button to reflect creating a new application and not a new job.

[nswalters]

Applications are what drive the changes, so we should make that workflow as easy as possible.

As part of creating an application, the user will have the ability to create a new company and job along with the application all in one go.

Therefore, the quick action should be to create an application and not just a new job.

[nswalters]

This won't be needed until/unless we have additional fields on an application, as currently all of the fields, other than the job an application is tied to, are automatically set upon creation.

Instead, maybe we change this to a more generic '+'-type button where it allows us to select what actions we take. It could include:

• Add a Company
• Add a Job
• Apply to Job (which will be added only if/after we have additional fields that require a separate form)

[nswalters]

This button has already been normalized as a '+ New...' button which takes the user to a page where they can add a new company and/or a new job.

Applying for jobs comes after while viewing the job list page (which may change later...)

Closing for now as won't fix.
