Add watermarking permissions and source flags to file and folder schemas to support review in src/schemas/fileFull.ts and src/schemas/folderFull.ts

Add canApplyWatermark to permissions and add isWatermarkInherited and isWatermarkedByAccessPolicy to watermark info, with serialization/deserialization and boolean validation updates across file and folder schemas.

📍Where to Start

Start with the deserializers deserializeFileFullPermissionsField and deserializeFolderFullPermissionsField in src/schemas/fileFull.ts and src/schemas/folderFull.ts, then review the corresponding watermark info serializers/deserializers.
