Previously with HTTP API enabled on brenchmarking run, it is possible
to cause a segfault due to an issue handling the m_httpd pointer and
rebinding.
- Initialize m_httpd to nullptr to indicate when it's not in use.
- Safely delete m_httpd in Api's destructor to prevent use-after-free
issues.
- Add checks to ensure m_httpd is not nullptr before usage in start,
stop, and tick methods.
- Log errors for HTTP server start failures to aid in debugging.
