Add Setting to enable/disable certificate verification

**Is your feature request related to a problem? Please describe.**
When testing mTLS connections, it might be desirable for Trufos to throw an error when calling hosts with unverifiable certificates. A toggle would be helpful.

**Describe the solution you'd like**
A toggle to disable or enable secure connections in the undici dispatcher.

**Describe alternatives you've considered**

**Additional context**

Start by locating the undici dispatcher configuration and how Trufos creates its connections. Verify the setting can enable or disable certificate verification for mTLS hosts, and add coverage for both toggle states.
