Describe the bug The blob storage is set to BLOB_STORAGE=s3 and a S3 bucket is configured, but the blob data is written to the database.

DEBUG [2023-07-20T07:39:19Z] [BOOTSTRAP] Service 'blobstorage.S3' has been initialized.
...
DEBUG [2023-07-20T07:41:06Z] [WEB] INSERT INTO attachments (tenant_id, post_id, comment_id, user_id, attachment_bkey) VALUES ($1, $2, $3, $4, $5) [1 2 {0 
false} 1 attachments/FX2QokiWDd1fjFGzXEdoRMy54og2unDmg3be2T6z1KHIFQ16fYtGyEeJ7W0Vkgop-foo.png] executed in 0ms

To Reproduce

• Configure a S3 storage with the environment variables in Fider:

  BLOB_STORAGE=s3
  BLOB_STORAGE_S3_ENDPOINT_URL
  BLOB_STORAGE_S3_BUCKET
  BLOB_STORAGE_S3_ACCESS_KEY_ID
  BLOB_STORAGE_S3_REGION
  BLOB_STORAGE_S3_SECRET_ACCESS_KEY

• Set the LOG_LEVEL to DEBUG
• Upload an image in Fider and check the S3 bucket and the log output.

Expected behavior Fider should write blob data like images into the S3 bucket.
