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 four admin-only endpoints under /api/admin/settings:
- GET / — full config (secrets redacted)
- GET /{module} — single module config
- PUT /{module} — toggle modules + persist config overrides
- POST /{module}/test — test external connectivity (database, storage)
PUT publishes a settings.changed SSE event. Config overrides are
persisted for future hot-reload support; changes to database/storage/
server/schemas namespaces return restart_required: true.
Wires SettingsRepository into Server struct.
