Ramkumar Chinchani 35c29b95e4 fix(security): limit manifest PUT body to 4 MiB (INPUT-1) (#3977)
Wrap request.Body with http.MaxBytesReader before io.ReadAll in
UpdateManifest. Bodies exceeding MaxManifestBodySize (4 MiB) now
return HTTP 413 with a MANIFEST_INVALID error body instead of
buffering unlimited data into memory.

Add the MaxManifestBodySize constant and a unit test that sends an
oversized body and asserts the 413 status.
