Problem

Fixes #221
Fixes #214

Approach

• Add UI component for uploading zip to external data #221: Add a UI function to Run > Files that allows user to import a BDBag-formatted ZIP file.
• LogLevel order seems strange (e.g. Info doesn't report errors) #214: Re-order log levels to make more sense (errors should now always be shown, rest are optional)

How to Test

Prerequisites: at least one Tale created

1. Checkout this branch locally, rebuild the dashboard
2. Login to the WholeTale Dashboard
3. Navigate to Run > Files > External Data for a Tale that you own
4. Expand the dropdown at the top-right

6. Wait for the upload/import to complete
7. Expand the dropdown at the top-right once more and choose "WT Data Catalog"
