Interruptible uploads

[paigewilliams]

PR against the develop branch!

Part 1 of allowing for interruptible/resumable uploads for Media in the Admin panel. Part 2 is in the django-resumable-async-upload repo.

Description

Uses the django-resumable-async-upload package to allow for uploads of media files to be interruptible. Details on how that works are in that packages repo.

The package is used in TEKDB in the following ways:

• For Media records, uses the AsyncFileField model instead of the FileField
• For MediaBulkUploads admin form, uses the FormResumableFileField to allow for resumable uploads.
• Allows for a max_files to be passed to the AsyncFileField to determine how many files can be uploaded to a file input

To do:

• Once django-resumable-async-upload package is published, use published package. Ensure tests pass in GH action once that is complete.
• Make a migration to use AsyncFileField
• Maybe: schedule a cron job that deletes chunks that runs every 24 (?) , 48 (?) hours. These chunks would exist in the case that an upload partially completes and the user does not try again to upload the file. This should come in a follow up PR.

Pull request overview

This PR integrates the django-resumable-async-upload package to support interruptible/resumable media uploads in the admin, focusing on Media records and bulk media uploads.

Changes:

• Add django-resumable-async-upload as a dependency and configure it in INSTALLED_APPS, URL routing, and project-level settings (e.g., admin resumable config).
• Switch Media.mediafile from FileField to AsyncFileField and update the bulk media upload form/admin logic to work with resumable uploads (using FormResumableMultipleFileField and ResumableAdminWidget and saving via cleaned file path lists).
• Update admin tests and supporting widgets/forms/migrations to align with the new resumable upload workflow and remove the legacy thumbnail file input widget.

The PR description states that OrphanedFileCleanupMiddleware is used and that the Media and MediaBulkUpload admin forms use AsyncFileCleanupMixin, but I don’t see that middleware added to MIDDLEWARE or the mixin applied to the relevant admin classes; as written, resumable uploads may leave orphaned files that are never cleaned up. Please either wire up the middleware/mixins as described or update the PR description (and any related docs) to match the actual behavior in this change set.
