bugfix: HTTPD start fails due to incorrect configuration

HomeKit code was starting HTTP Server with some fixed configuration.
Newer esp-idf versions (v5.2) introduced some new configurations that
were staying un-initiased, causing http server to fail to start.
Initialising with HTTPD_DEFAULT_CONFIG and then overriding relevant
values fixes the issue.
