successResponse() used NextResponse.json(), which calls JSON.stringify and
throws on BigInt. Prisma returns BigInt for VideoVersion.sizeBytes and
VideoAsset.sizeBytes, so any route returning one of those rows returned 500
after its database write had already committed.
#27 fixed two such endpoints by narrowing their selects, and two create
routes were already wrapped in toJsonSafe(). This closes the bug class at
the helper instead: successResponse() now serializes with a shared
bigIntReplacer, which covers every route in app/api (none construct a
NextResponse.json response directly).
The two toJsonSafe() call sites are now redundant and were removed. BigInt
values render as strings, matching what toJsonSafe already produced.
