every multipart upload through /api/<sidecar>/* arrived corrupted. bodyParser ran on
proxy routes and called parseBody for multipart, so hono cached a FormData on the
request; when the proxy then asked for the bytes hono re-serialised them from that
cache with a NEW boundary, while the proxy still forwarded the ORIGINAL content-type
header. header and body disagreed and the far side rejected it with
"Multipart: Unexpected end of form".
bodyParser now skips prefixes owned by createSidecarProxy, which register themselves
so a new sidecar cannot forget. the proxy also forwards the body as a stream instead
of buffering it, which drops the second in-memory copy of every upload.
note the bug report proposed skipping multipart in bodyParser outright; that would
have broken /upload, /file-browser upload and /bug-report, which do read a multipart
body from ctx.get('body').

bodyParser caught parse failures and did nothing — the throw was commented out
and `body` was never set, so handlers destructured undefined and the client got
a 500 for a malformed request. Throw BAD_REQUEST instead.
Also adds the regression tests for the Host suffix match fixed in 2ca850c.
Verified against a running server: malformed JSON now 400, valid credentials
path still 401, spoofed Host still 403.
