feat: add multipart image uploads

Register Fastify multipart support, validate JPEG/PNG/WebP binary signatures, store upload bytes through ImageStorage, persist metadata after storage succeeds, clean up bytes on metadata failure, and document the upload boundary. Verification: npm test passed 68 tests and integration passed 14 tests. No build script is configured.

 The metadata service currently enforces JPEG, PNG, and WebP MIME types, a
 10 MiB default file-size limit, and a 10,000-pixel maximum width and height.
-Binary signature checks and multipart upload validation remain part of the
-upload transport slice.
+Multipart upload validation now checks the declared MIME type against JPEG,
+PNG, and WebP signatures before storage. Image dimensions are supplied by the
+upload transport until a decoder-backed dimension extractor is added.
