Removes 12 direct minioClient.{put,get,remove}Object call sites that
bypassed the pluggable storage abstraction. Filesystem-mode deploys
(MULTI_NODE_DEPLOYMENT=false, storage_backend=filesystem) silently
broke at every site: GDPR export, invoice PDF, EOI generation, portal
download, file upload, folder create/rename/delete, signed PDF land,
maintenance cleanup, etc. Each site now resolves the active backend
and uses its put/get/delete + the new presignDownloadUrl() helper.
Folder marker objects in /files/folders/* keep the same on-the-wire
shape but route through the backend. A future refactor should move
folder bookkeeping to a DB-backed virtual-folder table (see audit
HIGH §3 follow-up note in the route file).
Sites left untouched: src/lib/services/system-monitoring.service.ts
and src/app/api/ready/route.ts use minioClient.bucketExists as an S3-
specific health probe — those are correctly mode-aware and stay.
