fix: add catch-all S3 route for path-style requests (/{bucket}/{key})

Bun's '/' route only matches root path '/'. S3 SDK clients using
forcePathStyle:true send ALL requests to /{bucket}/{key} which never
matched any route → 404. Added '/*' catch-all that checks for S3
auth headers before dispatching.
