Restore database from s3 file failing

[rngadam]

The restore file fails:

I'm able to run restore-db.sh locally successfully, but in the deploy.yml workflow I'm getting this error:

Step 0: Checking S3 backup bucket write access...
⚠️ Warning: No write access to S3 backup bucket (backups.cv.coderbunker.ca). Skipping pre-deployment backup.
👉 Note: This is expected if you are using a Read-Only staging key for production backups.
Step 0.2: Restoring database from backup-cv.coderbunker.ca-20260122103417.sql.enc...

fatal error: An error occurred (400) when calling the HeadObject operation: Bad Request

but with the permission fix, deployment works so I'll look at this issue later.
