Fix broken server references from reworking __init__.py and imports

A big database and import MR previously went out and fixing the imports on the servers was accidentally broken. This MR fixes it by directly referencing app in geomagio.api.app in both the production and localdev docker entrypoints. It also fixes the app variable name being changed and fixes a missed broken import.
