Rewire the source-document staging writes onto the unified storage layer
(INV-STG1), replacing direct shutil.copy2 calls:
- tools/documents.py: case originals + training-corpus uploads
- services/ingest.py: _stage_file (now async) — covers precedent-library,
internal-decisions, and digests (the canonical intake helper)
- services/digest_library.py: awaits the now-async _stage_file
Each write goes through storage.put_file(..., bucket=DOCUMENTS) with the
DATA_DIR-relative key; the Hebrew original filename rides as object metadata
(INV-STG2), content-type is guessed from the extension. DB path columns are
unchanged (still the absolute dest) — object_key backfill is Phase 3.
Under the default STORAGE_BACKEND=filesystem the bytes land at the exact
legacy on-disk location (put_file → shutil.copy2 to DATA_DIR/key), so this
is zero behaviour change in prod. shutil import dropped where now unused.
tests: +2 staging regression tests (file lands under DATA_DIR at the legacy
path); 20 storage + 22 ingest tests green; 242 collected with no import
breakage.
Derived/export write sites (thumbnails, extracted text, DOCX exports) are
Phase 2b. Keeps G2; advances INV-STG1. Spec: docs/spec/X14-storage-minio.md.
