fix: authorize the http connection to call commands (#2863)

fix: authorize the http connection to call DF commands

The assumption is that basic-auth already covers the authentication part.
And thanks to @sunneydev for finding the bug and providing the tests.
The tests actually uncovered another bug where we may parse partial http requests.
This one is handled by romange/helio#243
