Decrypt and persist all file metadata layers

Extends RawEnteFile and EnteFile with optional magicMetadata and
pubMagicMetadata fields. Both are secretstream blobs under the file
key, decrypted to arbitrary JSON (Record<string, unknown>).

pubMagicMetadata carries ML-derived data from the Ente clients:
camera make/model, image dimensions, datetime with timezone offset,
and (when present) captions, editedName, face labels, keywords.

magicMetadata carries private mutable fields like visibility.

Backup now writes per-file JSON at originals/<fileID>.json containing
all three metadata layers (basic + magic + pubMagic).

Live-tested: all 11 files in the dev account have pubMagicMetadata
with SONY DSC-RX1RM3 camera info and 3000x2000 dimensions.
