Remove the MinIO/S3 storage backend entirely. The filesystem backend is
fully implemented, already used in production, and a migrate-storage tool
exists for any remaining MinIO deployments to migrate beforehand.
Changes:
- Delete MinIO client implementation (internal/storage/storage.go)
- Delete migrate-storage tool (cmd/migrate-storage, scripts/migrate-storage.sh)
- Remove MinIO service, volumes, and env vars from all Docker Compose files
- Simplify StorageConfig: remove Endpoint, AccessKey, SecretKey, Bucket,
UseSSL, Region fields; add SILO_STORAGE_ROOT_DIR env override
- Change all SQL COALESCE defaults from 'minio' to 'filesystem'
- Add migration 020 to update column defaults to 'filesystem'
- Remove minio-go/v7 dependency (go mod tidy)
- Update all config examples, setup scripts, docs, and tests
Add three new endpoints that bypass the MinIO presigned URL flow:
- POST /api/items/{pn}/files/upload — multipart file upload
- POST /api/items/{pn}/thumbnail/upload — multipart thumbnail upload
- GET /api/items/{pn}/files/{fileId}/download — stream file download
Rewrite frontend upload flow: files are held in browser memory on drop
and uploaded directly after item creation via multipart POST. The old
presign+associate endpoints remain for MinIO backward compatibility.
Closes#129
