Describe this PR

• Configure Central so submission media automatically syncs to S3 (24hr schedule).
• Optionally trigger the sync on a more frequent interval (perhaps whenever submissions are requested).
• Implement some additional async functions in osm-fieldwork OdkCentralAsync to handle getting all pre-signed URLs for media attached to a submission.
• Replace custom logic in backend API with logic from osm-fieldwork to get the submission media pre-signed URLs via S3.
• Return the pre-signed URLs to the frontend for display.
• Deploy ODK Central on prod with env vars and S3 bucket set up
• Remove logic from FMTM that handled upload to the fmtm-data S3 bucket (replaced by ODK logic)
• Remove photo uploads added fmtm-data bucket on prod
